/**
 * An injectable service that produces an animation sequence programmatically within an
 * Angular component or directive.
 * Provided by the `BrowserAnimationsModule` or `NoopAnimationsModule`.
 *
 * @usageNotes
 *
 * To use this service, add it to your component or directive as a dependency.
 * The service is instantiated along with your component.
 *
 * Apps do not typically need to create their own animation players, but if you
 * do need to, follow these steps:
 *
 * 1. Use the `build()` method to create a programmatic animation using the
 * `animate()` function. The method returns an `AnimationFactory` instance.
 *
 * 2. Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.
 *
 * 3. Use the player object to control the animation programmatically.
 *
 * For example:
 *
 * ```ts
 * // import the service from BrowserAnimationsModule
 * import {AnimationBuilder} from '@angular/animations';
 * // require the service as a dependency
 * class MyCmp {
 *   constructor(private _builder: AnimationBuilder) {}
 *
 *   makeAnimation(element: any) {
 *     // first define a reusable animation
 *     const myAnimation = this._builder.build([
 *       style({ width: 0 }),
 *       animate(1000, style({ width: '100px' }))
 *     ]);
 *
 *     // use the returned factory object to create a player
 *     const player = myAnimation.create(element);
 *
 *     player.play();
 *   }
 * }
 * ```

/**
 * Creates a named animation trigger, containing a  list of `state()`
 * and `transition()` entries to be evaluated when the expression
 * bound to the trigger changes.
 *
 * @param name An identifying string.
 * @param definitions  An animation definition object, containing an array of `state()`
 * and `transition()` declarations.
 *
 * @return An object that encapsulates the trigger data.
 *
 * @usageNotes
 * Define an animation trigger in the `animations` section of `@Component` metadata.
 * In the template, reference the trigger by name and bind it to a trigger expression that
 * evaluates to a defined animation state, using the following format:
 *
 * `[@triggerName]="expression"`
 *
 * Animation trigger bindings convert all values to strings, and then match the
 * previous and current values against any linked transitions.
 * Booleans can be specified as `1` or `true` and `0` or `false`.
 *
 * ### Usage Example
 *
 * The following example creates an animation trigger reference based on the provided
 * name value.
 * The provided animation value is expected to be an array consisting of state and
 * transition declarations.
 *
 * ```typescript
 * @Component({
 *   selector: "my-component",
 *   templateUrl: "my-component-tpl.html",
 *   animations: [
 *     trigger("myAnimationTrigger", [
 *       state(...),
 *       state(...),
 *       transition(...),
 *       transition(...)
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "something";
 * }
 * ```
 *
 * The template associated with this component makes use of the defined trigger
 * by binding to an element within its template code.
 *
 * ```html
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * ### Using an inline function
 * The `transition` animation method also supports reading an inline function which can decide
 * if its associated animation should be run.
 *
 * ```typescript
 * // this method is run each time the `myAnimationTrigger` trigger value changes.
 * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
 string]: any}): boolean {
 *   // notice that `element` and `params` are also available here
 *   return toState == 'yes-please-animate';
 * }
 *
 * @Component({
 *   selector: 'my-component',
 *   templateUrl: 'my-component-tpl.html',
 *   animations: [
 *     trigger('myAnimationTrigger', [
 *       transition(myInlineMatcherFn, [
 *         // the animation sequence code
 *       ]),
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "yes-please-animate";
 * }
 * ```
 *
 * ### Disabling Animations
 * When true, the special animation control binding `@.disabled` binding prevents
 * all animations from rendering.
 * Place the  `@.disabled` binding on an element to disable
 * animations on the element itself, as well as any inner animation triggers
 * within the element.
 *
 * The following example shows how to use this feature:
 *
 * ```typescript
 * @Component({
 *   selector: 'my-component',
 *   template: `
 *     <div [@.disabled]="isDisabled">
 *       <div [@childAnimation]="exp"></div>
 *     </div>
 *   `,
 *   animations: [
 *     trigger("childAnimation", [
 *       // ...
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   isDisabled = true;
 *   exp = '...';
 * }
 * ```
 *
 * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,
 * along with any inner animations.
 *
 * ### Disable animations application-wide
 * When an area of the template is set to have animations disabled,
 * **all** inner components have their animations disabled as well.
 * This means that you can disable all animations for an app
 * by placing a host binding set on `@.disabled` on the topmost Angular component.
 *
 * ```typescript
 * import {Component, HostBinding} from '@angular/core';
 *
 * @Component({
 *   selector: 'app-component',
 *   templateUrl: 'app.component.html',
 * })
 * class AppComponent {
 *   @HostBinding('@.disabled')
 *   public animationsDisabled = true;
 * }
 * ```
 *
 * ### Overriding disablement of inner animations
 * Despite inner animations being disabled, a parent animation can `query()`
 * for inner elements located in disabled areas of the template and still animate
 * them if needed. This is also the case for when a sub animation is
 * queried by a parent and then later animated using `animateChild()`.
 *
 * ### Detecting when an animation is disabled
 * If a region of the DOM (or the entire application) has its animations disabled, the animation
 * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides
 * an instance of an `AnimationEvent`. If animations are disabled,
 * the `.disabled` flag on the event is true.
 *

/**
 * Defines an animation step that combines styling information with timing information.
 *
 * @param timings Sets `AnimateTimings` for the parent animation.
 * A string in the format "duration [delay] [easing]".
 *  - Duration and delay are expressed as a number and optional time unit,
 * such as "1s" or "10ms" for one second and 10 milliseconds, respectively.
 * The default unit is milliseconds.
 *  - The easing value controls how the animation accelerates and decelerates
 * during its runtime. Value is one of  `ease`, `ease-in`, `ease-out`,
 * `ease-in-out`, or a `cubic-bezier()` function call.
 * If not supplied, no easing is applied.
 *
 * For example, the string "1s 100ms ease-out" specifies a duration of
 * 1000 milliseconds, and delay of 100 ms, and the "ease-out" easing style,
 * which decelerates near the end of the duration.
 * @param styles Sets AnimationStyles for the parent animation.
 * A function call to either `style()` or `keyframes()`
 * that returns a collection of CSS style entries to be applied to the parent animation.
 * When null, uses the styles from the destination state.
 * This is useful when describing an animation step that will complete an animation;
 * see "Animating to the final state" in `transitions()`.
 * @returns An object that encapsulates the animation step.
 *
 * @usageNotes
 * Call within an animation `sequence()`, `{@link animations/group group()}`, or
 * `transition()` call to specify an animation step
 * that applies given style data to the parent animation for a given amount of time.
 *
 * ### Syntax Examples
 * **Timing examples**
 *
 * The following examples show various `timings` specifications.
 * - `animate(500)` : Duration is 500 milliseconds.
 * - `animate("1s")` : Duration is 1000 milliseconds.
 * - `animate("100ms 0.5s")` : Duration is 100 milliseconds, delay is 500 milliseconds.
 * - `animate("5s ease-in")` : Duration is 5000 milliseconds, easing in.
 * - `animate("5s 10ms cubic-bezier(.17,.67,.88,.1)")` : Duration is 5000 milliseconds, delay is 10
 * milliseconds, easing according to a bezier curve.
 *
 * **Style examples**
 *
 * The following example calls `style()` to set a single CSS style.
 * ```typescript
 * animate(500, style({ background: "red" }))
 * ```
 * The following example calls `keyframes()` to set a CSS style
 * to different values for successive keyframes.
 * ```typescript
 * animate(500, keyframes(
 *  [
 *   style({ background: "blue" })),
 *   style({ background: "red" }))
 *  ])
 * ```

/**
 * Declares an animation transition as a sequence of animation steps to run when a given

 * triggered.
 *
 * @param stateChangeExpr A Boolean expression or function that compares the previous and current

 * animation trigger element.
 * The animation steps run when the expression evaluates to true.
 *
 * - A state-change string takes the form "state1 => state2", where each side is a defined animation
 * state, or an asterix (*) to refer to a dynamic start or end state.
 *   - The expression string can contain multiple comma-separated statements;
 * for example "state1 => state2, state3 => state4".
 *   - Special values `:enter` and `:leave` initiate a transition on the entry and exit states,
 * equivalent to  "void => *"  and "* => void".
 *   - Special values `:increment` and `:decrement` initiate a transition when a numeric value has
 * increased or decreased in value.

 * and additional developer-defined parameters. Provided values for additional parameters are used
 * as defaults, and override values can be passed to the caller on invocation.
 * @returns An object that encapsulates the transition data.
 *
 * @usageNotes
 * The template associated with a component binds an animation trigger to an element.
 *
 * ```HTML
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * All transitions are defined within an animation trigger,
 * along with named states that the transitions change to and from.
 *
 * ```typescript
 * trigger("myAnimationTrigger", [
 *  // define states
 *  state("on", style({ background: "green" })),
 *  state("off", style({ background: "grey" })),
 *  ...]
 * ```
 *
 * Note that when you call the `sequence()` function within a `{@link animations/group group()}`
 * or a `transition()` call, execution does not continue to the next instruction
 * until each of the inner animation steps have completed.
 *
 * ### Syntax examples
 *
 * The following examples define transitions between the two defined states (and default states),
 * using various options:
 *
 * ```typescript
 * // Transition occurs when the state value
 * // bound to "myAnimationTrigger" changes from "on" to "off"
 * transition("on => off", animate(500))
 * // Run the same animation for both directions
 * transition("on <=> off", animate(500))
 * // Define multiple state-change pairs separated by commas
 * transition("on => off, off => void", animate(500))
 * ```
 *
 * ### Special values for state-change expressions
 *
 * - Catch-all state change for when an element is inserted into the page and the
 * destination state is unknown:
 *
 * ```typescript
 * transition("void => *", [
 *  style({ opacity: 0 }),
 *  animate(500)
 *  ])
 * ```
 *
 * - Capture a state change between any states:
 *
 *  `transition("* => *", animate("1s 0s"))`
 *
 * - Entry and exit transitions:
 *
 * ```typescript
 * transition(":enter", [
 *   style({ opacity: 0 }),
 *   animate(500, style({ opacity: 1 }))
 *   ]),
 * transition(":leave", [
 *   animate(500, style({ opacity: 0 }))
 *   ])
 * ```
 *
 * - Use `:increment` and `:decrement` to initiate transitions:
 *
 * ```typescript
 * transition(":increment", group([
 *  query(':enter', [
 *     style({ left: '100%' }),
 *     animate('0.5s ease-out', style('*'))
 *   ]),
 *  query(':leave', [
 *     animate('0.5s ease-out', style({ left: '-100%' }))
 *  ])
 * ]))
 *
 * transition(":decrement", group([
 *  query(':enter', [
 *     style({ left: '100%' }),
 *     animate('0.5s ease-out', style('*'))
 *   ]),
 *  query(':leave', [
 *     animate('0.5s ease-out', style({ left: '-100%' }))
 *  ])
 * ]))
 * ```
 *
 * ### State-change functions
 *
 * Here is an example of a `fromState` specified as a state-change function that invokes an
 * animation when true:
 *
 * ```typescript
 * transition((fromState, toState) =>
 *  {
 *   return fromState == "off" && toState == "on";
 *  },
 *  animate("1s 0s"))
 * ```
 *
 * ### Animating to the final state
 *
 * If the final step in a transition is a call to `animate()` that uses a timing value
 * with no style data, that step is automatically considered the final animation arc,
 * for the element to reach the final state. Angular automatically adds or removes
 * CSS styles to ensure that the element is in the correct final state.
 *
 * The following example defines a transition that starts by hiding the element,
 * then makes sure that it animates properly to whatever state is currently active for trigger:
 *
 * ```typescript
 * transition("void => *", [
 *   style({ opacity: 0 }),
 *   animate(500)
 *  ])
 * ```
 * ### Boolean value matching
 * If a trigger binding value is a Boolean, it can be matched using a transition expression
 * that compares true and false or 1 and 0. For example:
 *
 * ```
 * // in the template
 * <div [@openClose]="open ? true : false">...</div>
 * // in the component metadata
 * trigger('openClose', [
 *   state('true', style({ height: '*' })),
 *   state('false', style({ height: '0px' })),
 *   transition('false <=> true', animate(500))
 * ])
 * ```

 * and transitions are not handled by this API.

/**
 * Finds one or more inner elements within the current element that is
 * being animated within a sequence. Use with `animate()`.
 *
 * @param selector The element to query, or a set of elements that contain Angular-specific
 * characteristics, specified with one or more of the following tokens.
 *  - `query(":enter")` or `query(":leave")` : Query for newly inserted/removed elements.
 *  - `query(":animating")` : Query all currently animating elements.
 *  - `query("@triggerName")` : Query elements that contain an animation trigger.
 *  - `query("@*")` : Query all elements that contain an animation triggers.
 *  - `query(":self")` : Include the current element into the animation sequence.
 *
 * @param animation One or more animation steps to apply to the queried element or elements.
 * An array is treated as an animation sequence.
 * @param options An options object. Use the 'limit' field to limit the total number of
 * items to collect.
 * @return An object that encapsulates the query data.
 *
 * @usageNotes
 * Tokens can be merged into a combined query selector string. For example:
 *
 * ```typescript
 *  query(':self, .record:enter, .record:leave, @subTrigger', [...])
 * ```
 *
 * The `query()` function collects multiple elements and works internally by using
 * `element.querySelectorAll`. Use the `limit` field of an options object to limit
 * the total number of items to be collected. For example:
 *
 * ```js
 * query('div', [
 *   animate(...),
 *   animate(...)
 * ], { limit: 1 })
 * ```
 *
 * By default, throws an error when zero items are found. Set the
 * `optional` flag to ignore this error. For example:
 *
 * ```js
 * query('.some-element-that-may-not-be-there', [
 *   animate(...),
 *   animate(...)
 * ], { optional: true })
 * ```
 *
 * ### Usage Example
 *
 * The following example queries for inner elements and animates them
 * individually using `animate()`.
 *
 * ```typescript
 * @Component({
 *   selector: 'inner',
 *   template: `
 *     <div [@queryAnimation]="exp">
 *       <h1>Title</h1>
 *       <div class="content">
 *         Blah blah blah
 *       </div>
 *     </div>
 *   `,
 *   animations: [
 *    trigger('queryAnimation', [
 *      transition('* => goAnimate', [
 *        // hide the inner elements
 *        query('h1', style({ opacity: 0 })),
 *        query('.content', style({ opacity: 0 })),
 *
 *        // animate the inner elements in, one by one
 *        query('h1', animate(1000, style({ opacity: 1 }))),
 *        query('.content', animate(1000, style({ opacity: 1 }))),
 *      ])
 *    ])
 *  ]
 * })
 * class Cmp {
 *   exp = '';
 *
 *   goAnimate() {
 *     this.exp = 'goAnimate';
 *   }
 * }
 * ```
 *
 * @publicApi
 */

/**
 * Use within an animation `query()` call to issue a timing gap after
 * each queried item is animated.
 *
 * @param timings A delay value.
 * @param animation One ore more animation steps.
 * @returns An object that encapsulates the stagger data.
 *
 * @usageNotes
 * In the following example, a container element wraps a list of items stamped out
 * by an `ngFor`. The container element contains an animation trigger that will later be set
 * to query for each of the inner items.
 *
 * Each time items are added, the opacity fade-in animation runs,
 * and each removed item is faded out.
 * When either of these animations occur, the stagger effect is
 * applied after each item's animation is started.
 *
 * ```html
 * <!-- list.component.html -->
 * <button (click)="toggle()">Show / Hide Items</button>
 * <hr />
 * <div [@listAnimation]="items.length">
 *   <div *ngFor="let item of items">
 *     {{ item }}
 *   </div>
 * </div>
 * ```
 *
 * Here is the component code:
 *
 * ```typescript
 * import {trigger, transition, style, animate, query, stagger} from '@angular/animations';
 * @Component({
 *   templateUrl: 'list.component.html',
 *   animations: [
 *     trigger('listAnimation', [
 *     ...
 *     ])
 *   ]
 * })
 * class ListComponent {
 *   items = [];
 *
 *   showItems() {
 *     this.items = [0,1,2,3,4];
 *   }
 *
 *   hideItems() {
 *     this.items = [];
 *   }
 *
 *   toggle() {
 *     this.items.length ? this.hideItems() : this.showItems();
 *    }
 *  }
 * ```
 *
 * Here is the animation trigger code:
 *
 * ```typescript
 * trigger('listAnimation', [
 *   transition('* => *', [ // each time the binding value changes
 *     query(':leave', [
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 0 }))
 *       ])
 *     ]),
 *     query(':enter', [
 *       style({ opacity: 0 }),
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 1 }))
 *       ])
 *     ])
 *   ])
 * ])
 * ```

/*
 * [Validation]
 * The visitor code below will traverse the animation AST generated by the animation verb functions
 * (the output is a tree of objects) and attempt to perform a series of validations on the data. The
 * following corner-cases will be validated:
 *
 * 1. Overlap of animations
 * Given that a CSS property cannot be animated in more than one place at the same time, it's
 * important that this behavior is detected and validated. The way in which this occurs is that
 * each time a style property is examined, a string-map containing the property will be updated with
 * the start and end times for when the property is used within an animation step.
 *
 * If there are two or more parallel animations that are currently running (these are invoked by the
 * group()) on the same element then the validator will throw an error. Since the start/end timing
 * values are collected for each property then if the current animation step is animating the same
 * property and its timing values fall anywhere into the window of time that the property is
 * currently being animated within then this is what causes an error.
 *
 * 2. Timing values
 * The validator will validate to see if a timing value of `duration delay easing` or
 * `durationNumber` is valid or not.
 *
 * (note that upon validation the code below will replace the timing data with an object containing
 * {duration,delay,easing}.
 *
 * 3. Offset Validation
 * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
 * Offsets within keyframes() are considered valid when:
 *
 *   - No offsets are used at all
 *   - Each style() entry contains an offset value
 *   - Each offset is between 0 and 1
 *   - Each offset is greater to or equal than the previous one
 *
 * Otherwise an error will be thrown.

/*
 * The code within this file aims to generate web-animations-compatible keyframes from Angular's
 * animation DSL code.
 *
 * The code below will be converted from:
 *
 * ```
 * sequence([
 *   style({ opacity: 0 }),
 *   animate(1000, style({ opacity: 0 }))
 * ])
 * ```
 *
 * To:
 * ```
 * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
 * duration = 1000
 * delay = 0
 * easing = ''
 * ```
 *
 * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
 * combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.
 *
 * [AST Traversal]
 * Each of the animation verbs, when executed, will return an string-map object representing what
 * type of action it is (style, animate, group, etc...) and the data associated with it. This means
 * that when functional composition mix of these functions is evaluated (like in the example above)
 * then it will end up producing a tree of objects representing the animation itself.
 *
 * When this animation object tree is processed by the visitor code below it will visit each of the
 * verb statements within the visitor. And during each visit it will build the context of the
 * animation keyframes by interacting with the `TimelineBuilder`.
 *
 * [TimelineBuilder]
 * This class is responsible for tracking the styles and building a series of keyframe objects for a
 * timeline between a start and end time. The builder starts off with an initial timeline and each
 * time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a
 * `sequence()` then it will generate a sub timeline for each step as well as a new one after
 * they are complete.
 *
 * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
 * timeline was created (based on one of the cases above) then the parent timeline will attempt to
 * merge the styles used within the sub timelines into itself (only with group() this will happen).
 * This happens with a merge operation (much like how the merge works in mergesort) and it will only
 * copy the most recently used styles from the sub timelines into the parent timeline. This ensures
 * that if the styles are used later on in another phase of the animation then they will be the most
 * up-to-date values.
 *
 * [How Missing Styles Are Updated]
 * Each timeline has a `backFill` property which is responsible for filling in new styles into
 * already processed keyframes if a new style shows up later within the animation sequence.
 *
 * ```
 * sequence([
 *   style({ width: 0 }),
 *   animate(1000, style({ width: 100 })),
 *   animate(1000, style({ width: 200 })),
 *   animate(1000, style({ width: 300 }))
 *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
 * else
 * ])
 * ```
 *
 * What is happening here is that the `height` value is added later in the sequence, but is missing
 * from all previous animation steps. Therefore when a keyframe is created it would also be missing
 * from all previous keyframes up until where it is first used. For the timeline keyframe generation
 * to properly fill in the style it will place the previous value (the value from the parent
 * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe
 * styles are objects that prototypically inhert from the backFill object, this means that if a
 * value is added into the backFill then it will automatically propagate any missing values to all
 * keyframes. Therefore the missing `height` value will be properly filled into the already
 * processed keyframes.
 *
 * When a sub-timeline is created it will have its own backFill property. This is done so that
 * styles present within the sub-timeline do not accidentally seep into the previous/future timeline
 * keyframes
 *
 * (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)
 *
 * [Validation]
 * The code in this file is not responsible for validation. That functionality happens with within
 * the `AnimationValidatorVisitor` code.

 * agnostic.
 * This means that we can have different implementation of `PlatformLocation` for the different
 * platforms that angular supports. For example, `@angular/platform-browser` provides an
 * implementation specific to the browser environment, while `@angular/platform-webworker` provides
 * one suitable for use with web workers.
 *
 * The `PlatformLocation` class is used directly by all implementations of {@link LocationStrategy}
 * when they need to interact with the DOM apis like pushState, popState, etc...
 *
 * {@link LocationStrategy} in turn is used by the {@link Location} service which is used directly
 * by the {@link Router} in order to navigate between routes. Since all interactions between {@link
 * Router} /
 * {@link Location} / {@link LocationStrategy} and DOM apis flow through the `PlatformLocation`
 * class they are all platform independent.

 * @description
 *
 * A service that applications can use to interact with a browser's URL.
 *
 * Depending on the `LocationStrategy` used, `Location` will either persist
 * to the URL's path or the URL's hash segment.
 *
 * @usageNotes
 *
 * It's better to use the {@link Router#navigate} service to trigger route changes. Use
 * `Location` only if you need to interact with or create normalized URLs outside of
 * routing.
 *
 * `Location` is responsible for normalizing the URL against the application's base href.
 * A normalized URL is absolute from the URL host, includes the application's base href, and has no
 * trailing slash:
 * - `/my/app/user/123` is normalized
 * - `my/app/user/123` **is not** normalized
 * - `/my/app/user/123/` **is not** normalized

/**
 * Used to diff and convert ngStyle/ngClass instructions into [style] and [class] bindings.
 *
 * ngStyle and ngClass both accept various forms of input and behave differently than that
 * of how [style] and [class] behave in Angular.
 *
 * The differences are:
 *  - ngStyle and ngClass both **watch** their binding values for changes each time CD runs
 *    while [style] and [class] bindings do not (they check for identity changes)
 *  - ngStyle allows for unit-based keys (e.g. `{'max-width.px':value}`) and [style] does not
 *  - ngClass supports arrays of class values and [class] only accepts map and string values
 *  - ngClass allows for multiple className keys (space-separated) within an array or map
 *     (as the * key) while [class] only accepts a simple key/value map object
 *
 * Having Angular understand and adapt to all the different forms of behavior is complicated
 * and unnecessary. Instead, ngClass and ngStyle should have their input values be converted
 * into something that the core-level [style] and [class] bindings understand.
 *
 * This [StylingDiffer] class handles this conversion by creating a new input value each time
 * the inner representation of the binding value have changed.
 *
 * ## Why do we care about ngStyle/ngClass?
 * The styling algorithm code (documented inside of `render3/interfaces/styling.ts`) needs to
 * respect and understand the styling values emitted through ngStyle and ngClass (when they
 * are present and used in a template).
 *
 * Instead of having these directives manage styling on their own, they should be included
 * into the Angular styling algorithm that exists for [style] and [class] bindings.
 *
 * Here's why:
 *
 * - If ngStyle/ngClass is used in combination with [style]/[class] bindings then the
 *   styles and classes would fall out of sync and be applied and updated at
 *   inconsistent times
 * - Both ngClass/ngStyle do not respect [class.name] and [style.prop] bindings
 *   (they will write over them given the right combination of events)
 *
 *   ```
 *   <!-- if `w1` is updated then it will always override `w2`
 *        if `w2` is updated then it will always override `w1`
 *        if both are updated at the same time then `w1` wins -->
 *   <div [ngStyle]="{width:w1}" [style.width]="w2">...</div>
 *
 *   <!-- if `w1` is updated then it will always lose to `w2`
 *        if `w2` is updated then it will always override `w1`
 *        if both are updated at the same time then `w2` wins -->
 *   <div [style]="{width:w1}" [style.width]="w2">...</div>
 *   ```
 * - ngClass/ngStyle were written as a directives and made use of maps, closures and other
 *   expensive data structures which were evaluated each time CD runs

/**
 * Instantiates a single {@link Component} type and inserts its Host View into current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will get destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if exists.
 *
 * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow dynamically loading other
 * module, then load a component from that module.
 *
 * ### Syntax
 *
 * Simple
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * Customized injector/content
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized ngModuleFactory
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModuleFactory: moduleFactory;">
 * </ng-container>
 * ```
 *
 * ### A simple example
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}
 *
 * A more complete example with additional options:
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='CompleteExample'}

/**
 * A [structural directive](guide/structural-directives) that renders
 * a template for each item in a collection.
 * The directive is placed on an element, which becomes the parent
 * of the cloned templates.
 *
 * The `ngForOf` directive is generally used in the
 * [shorthand form](guide/structural-directives#the-asterisk--prefix) `*ngFor`.
 * In this form, the template to be rendered for each iteration is the content
 * of an anchor element containing the directive.
 *
 * The following example shows the shorthand syntax with some options,
 * contained in an `<li>` element.
 *
 * ```
 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
 * ```
 *
 * The shorthand form expands into a long form that uses the `ngForOf` selector
 * on an `<ng-template>` element.
 * The content of the `<ng-template>` element is the `<li>` element that held the
 * short-form directive.
 *
 * Here is the expanded version of the short-form example.
 *
 * ```
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * Angular automatically expands the shorthand syntax as it compiles the template.
 * The context for each embedded view is logically merged to the current component
 * context according to its lexical position.
 *
 * When using the shorthand syntax, Angular allows only [one structural directive
 * on an element](guide/structural-directives#one-structural-directive-per-host-element).
 * If you want to iterate conditionally, for example,
 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
 * For futher discussion, see
 * [Structural Directives](guide/structural-directives#one-per-element).
 *
 * @usageNotes
 *
 * ### Local variables
 *
 * `NgForOf` provides exported values that can be aliased to local variables.
 * For example:
 *
 *  ```
 * <li *ngFor="let user of userObservable | async as users; index as i; first as isFirst">
 *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
 * </li>
 * ```
 *
 * The following exported values can be aliased to local variables:
 *
 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
 * more complex then a property access, for example when using the async pipe (`userStreams |
 * async`).
 * - `index: number`: The index of the current item in the iterable.
 * - `first: boolean`: True when the item is the first item in the iterable.
 * - `last: boolean`: True when the item is the last item in the iterable.
 * - `even: boolean`: True when the item has an even index in the iterable.
 * - `odd: boolean`: True when the item has an odd index in the iterable.
 *
 * ### Change propagation
 *
 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
 * those changes in the DOM. This has important implications for animations and any stateful
 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
 *
 * The identities of elements in the iterator can change while the data does not.
 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted).
 *
 * To avoid this expensive operation, you can customize the default tracking algorithm.
 * by supplying the `trackBy` option to `NgForOf`.
 * `trackBy` takes a function that has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.
 *

/**
 * A structural directive that conditionally includes a template based on the value of
 * an expression coerced to Boolean.
 * When the expression evaluates to true, Angular renders the template
 * provided in a `then` clause, and when  false or null,
 * Angular renders the template provided in an optional `else` clause. The default
 * template for the `else` clause is blank.
 *
 * A [shorthand form](guide/structural-directives#the-asterisk--prefix) of the directive,
 * `*ngIf="condition"`, is generally used, provided
 * as an attribute of the anchor element for the inserted template.
 * Angular expands this into a more explicit version, in which the anchor element
 * is contained in an `<ng-template>` element.
 *
 * Simple form with shorthand syntax:
 *
 * ```
 * <div *ngIf="condition">Content to render when condition is true.</div>
 * ```
 *
 * Simple form with expanded syntax:
 *
 * ```
 * <ng-template [ngIf]="condition"><div>Content to render when condition is

 * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Form with storing the value locally:
 *
 * ```
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
 * ```
 *
 * @usageNotes
 *
 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
 * as seen in the following  example.
 * The default `else` template is blank.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * To display a template when `expression` evaluates to false, use an `else` template
 * binding as shown in the following example.
 * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
 * The template can be defined anywhere in the component view, but is typically placed right after
 * `ngIf` for readability.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
 *
 * ### Using an external `then` template
 *
 * In the previous example, the then-clause template is specified inline, as the content of the
 * tag that contains the `ngIf` directive. You can also specify a template that is defined
 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
 * change which template to use at runtime, as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing a conditional result in a variable
 *
 * You might want to show a set of properties from the same object. If you are waiting
 * for asynchronous data, the object can be undefined.
 * In this case, you can use `ngIf` and store the result of the condition in a local
 * variable as shown in the the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * This code uses only one `AsyncPipe`, so only one subscription is created.
 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
 * You can then bind the local `user` repeatedly.
 *
 * The conditional displays the data only if `userStream` returns a value,
 * so you don't need to use the
 * [safe-navigation-operator](guide/template-syntax#safe-navigation-operator) (`?.`)
 * to guard against null values when accessing properties.
 * You can display an alternative template while waiting for the data.
 *
 * ### Shorthand syntax
 *
 * The shorthand syntax `*ngIf` expands into two separate template specifications
 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
 * that is meant to show a loading page while waiting for data to be loaded.
 *
 * ```
 * <div class="hero-list" *ngIf="heroes else loading">
 *  ...
 * </div>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * You can see that the "else" clause references the `<ng-template>`
 * with the `#loading` label, and the template for the "then" clause
 * is provided as the content of the anchor element.
 *
 * However, when Angular expands the shorthand syntax, it creates
 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
 * The anchor element containing the template for the "then" clause becomes
 * the content of this unlabeled `<ng-template>` tag.
 *
 * ```
 * <ng-template [ngIf]="hero-list" [ngIfElse]="loading">
 *  <div class="hero-list">
 *   ...
 *  </div>
 * </ng-template>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * The presence of the implicit template object has implications for the nesting of
 * structural directives. For more on this subject, see
 * [Structural Directives](https://angular.io/guide/structural-directives#one-per-element).

/**
 * @ngModule CommonModule
 *
 * @description A structural directive that adds or removes templates (displaying or hiding views)
 * when the next match expression matches the switch expression.
 *
 * The `[ngSwitch]` directive on a container specifies an expression to match against.
 * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
 * - Every view that matches is rendered.
 * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
 * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
 * or `ngSwitchDefault` directive are preserved at the location.
 *
 * @usageNotes
 * Define a container element for the directive, and specify the switch expression
 * to match against as an attribute:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 * ```
 *
 * Within the container, `*ngSwitchCase` statements specify the match expressions
 * as attributes. Include `*ngSwitchDefault` as the final case.
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
 * ...
 *    <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * ### Usage Examples
 *
 * The following example shows how to use more than one case to display the same view:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *   <!-- the same view can be shown in more than one case -->
 *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *   <!--default case when there are no matches -->
 *   <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * The following example shows how cases can be nested:
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *       <ng-container *ngSwitchCase="match_expression_3">
 *         <!-- use a ng-container to group multiple root nodes -->
 *         <inner-element></inner-element>
 *         <inner-other-element></inner-other-element>
 *       </ng-container>
 *       <some-element *ngSwitchDefault>...</some-element>

 * In javascript, only the components specified will be respected (not the ordering,
 * punctuations, ...) and details of the formatting will be dependent on the locale.
 *
 * Timezone of the formatted text will be the local system timezone of the end-user's machine.
 *
 * When the expression is a ISO string without time (e.g. 2016-09-19) the time zone offset is not
 * applied and the formatted text will have the same day, month and year of the expression.
 *
 * WARNINGS:
 * - this pipe is marked as pure hence it will not be re-evaluated when the input is mutated.
 *   Instead users should treat the date as an immutable object and change the reference when the
 *   pipe needs to re-run (this is to avoid reformatting the date on every change detection run
 *   which would be an expensive operation).
 * - this pipe uses the Internationalization API. Therefore it is only reliable in Chrome and Opera
 *   browsers.

/**
 * @ngModule CommonModule
 * @description
 *
 * Formats a date value according to locale rules.
 *
 * Only the `en-US` locale data comes with Angular. To localize dates
 * in another language, you must import the corresponding locale data.
 * See the [I18n guide](guide/i18n#i18n-pipes) for more information.
 *
 * @see `formatDate()`
 *
 *
 * @usageNotes
 *
 * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
 * reformat the date on every change-detection cycle, treat the date as an immutable object
 * and change the reference when the pipe needs to run again.
 *
 * ### Pre-defined format options
 *
 * Examples are given in `en-US` locale.
 *
 * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).
 * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).
 * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM
 * GMT+1`).
 * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at
 * 9:03:01 AM GMT+01:00`).
 * - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).
 * - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).
 * - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).
 * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).
 * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).
 * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).
 * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).
 * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).
 *
 * ### Custom format options
 *
 * You can construct a format string using symbols to specify the components
 * of a date-time value, as described in the following table.
 * Format details depend on the locale.
 * Fields marked with (*) are only available in the extra data set for the given locale.

 * Note that timezone correction is not applied to an ISO string that has no time component, such as "2016-09-19"
 *
 * ### Format examples
 *
 * These examples transform a date into various formats,
 * assuming that `dateObj` is a JavaScript `Date` object for
 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
 * given in the local time for the `en-US` locale.
 *
 * ```
 * {{ dateObj | date }}               // output is 'Jun 15, 2015'
 * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
 * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
 * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
 * ```
 *
 * ### Usage example
 *
 * The following component uses a date pipe to display the current date in different formats.
 *
 * ```
 * @Component({
 *  selector: 'date-pipe',
 *  template: `<div>
 *    <p>Today is {{today | date}}</p>
 *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
 *    <p>The time is {{today | date:'h:mm a z'}}</p>
 *  </div>`
 * })
 * // Get the current date and time as a date-time value.
 * export class DatePipeComponent {
 *   today: number = Date.now();
 * }
 * ```

/*
  This is a limited shim for ShadowDOM css styling.
  https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles

  The intention here is to support only the styling features which can be
  relatively simply implemented. The goal is to allow users to avoid the
  most obvious pitfalls and do so without compromising performance significantly.
  For ShadowDOM styling that's not covered here, a set of best practices
  can be provided that should allow users to accomplish more complex styling.

  The following is a list of specific ShadowDOM styling features and a brief
  discussion of the approach used to shim.

  Shimmed features:

  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
  element using the :host rule. To shim this feature, the :host styles are
  reformatted and prefixed with a given scope name and promoted to a
  document level stylesheet.
  For example, given a scope name of .foo, a rule like this:

    :host {
        background: red;
      }
    }

  becomes:

    .foo {
      background: red;
    }

  * encapsulation: Styles defined within ShadowDOM, apply only to
  dom inside the ShadowDOM. Polymer uses one of two techniques to implement
  this feature.

  By default, rules are prefixed with the host element tag name
  as a descendant selector. This ensures styling does not leak out of the 'top'
  of the element's ShadowDOM. For example,

  div {
      font-weight: bold;
    }

  becomes:

  x-foo div {
      font-weight: bold;
    }

  becomes:


  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
  selectors are scoped by adding an attribute selector suffix to each
  simple selector that contains the host element tag name. Each element
  in the element's ShadowDOM template is also given the scope attribute.
  Thus, these rules match only elements that have the scope attribute.
  For example, given a scope name of x-foo, a rule like this:

    div {
      font-weight: bold;
    }

  becomes:

    div[x-foo] {
      font-weight: bold;
    }

  Note that elements that are dynamically added to a scope must have the scope
  selector added to them manually.

  * upper/lower bound encapsulation: Styles which are defined outside a
  shadowRoot should not cross the ShadowDOM boundary and should not apply
  inside a shadowRoot.

  This styling behavior is not emulated. Some possible ways to do this that
  were rejected due to complexity and/or performance concerns include: (1) reset
  every possible property for every possible selector for a given scope name;
  (2) re-implement css in javascript.

  As an alternative, users should make sure to use selectors
  specific to the scope in which they are working.

  * ::distributed: This behavior is not emulated. It's often not necessary
  to style the contents of a specific insertion point and instead, descendants
  of the host element can be styled selectively. Users can also create an
  extra node around an insertion point and style that node's contents
  via descendent selectors. For example, with a shadowRoot like this:

    <style>
      ::content(div) {
        background: red;
      }
    </style>
    <content></content>

  could become:

    <style>
      / *@polyfill .content-container div * /
      ::content(div) {
        background: red;
      }
    </style>
    <div class="content-container">
      <content></content>
    </div>

  Note the use of @polyfill in the comment above a ShadowDOM specific style
  declaration. This is a directive to the styling shim to use the selector
  in comments in lieu of the next selector when running under polyfill.

 * A path is an ordered set of elements. Typically a path is to  a

 * most node. The tail is the node that contains the offset directly.
 *
 * For example, the expression `a + b + c` might have an ast that looks
 * like:
 *     +
 *    / \
 *   a   +
 *      / \
 *     b   c
 *
 * The path to the node at offset 9 would be `['+' at 1-10, '+' at 7-10,
 * 'c' at 9-10]` and the path the node at offset 1 would be
 * `['+' at 1-10, 'a' at 1-2]`.

/**
 * This array represents the DOM schema. It encodes inheritance, properties, and events.
 *
 * ## Overview
 *
 * Each line represents one kind of element. The `element_inheritance` and properties are joined
 * using `element_inheritance|properties` syntax.
 *
 * ## Element Inheritance
 *
 * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
 * Here the individual elements are separated by `,` (commas). Every element in the list
 * has identical properties.
 *
 * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
 * specified then `""` (blank) element is assumed.
 *
 * NOTE: The blank element inherits from root `[Element]` element, the super element of all
 * elements.
 *
 * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
 *
 * ## Properties
 *
 * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
 * by a special character designating its type:
 *
 * - (no prefix): property is a string.
 * - `*`: property represents an event.
 * - `!`: property is a boolean.
 * - `#`: property is a number.
 * - `%`: property is an object.
 *
 * ## Query
 *
 * The class creates an internal squas representation which allows to easily answer the query of
 * if a given property exist on a given element.
 *
 * NOTE: We don't yet support querying for types or events.
 * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
 *       see dom_element_schema_registry_spec.ts

/**
 * A regular expression for breaking a URI into its component parts.
 *
 * {@link http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#RFC2234} says
 * As the "first-match-wins" algorithm is identical to the "greedy"
 * disambiguation method used by POSIX regular expressions, it is natural and
 * commonplace to use a regular expression for parsing the potential five
 * components of a URI reference.
 *
 * The following line is the regular expression for breaking-down a
 * well-formed URI reference into its components.
 *
 * <pre>
 * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
 *  12            3  4          5       6  7        8 9
 * </pre>
 *
 * The numbers in the second line above are only to assist readability; they
 * indicate the reference points for each subexpression (i.e., each paired
 * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
 * For example, matching the above expression to
 * <pre>
 *     http://www.ics.uci.edu/pub/ietf/uri/#Related
 * </pre>
 * results in the following subexpression matches:
 * <pre>
 *    $1 = http:
 *    $2 = http
 *    $3 = //www.ics.uci.edu
 *    $4 = www.ics.uci.edu
 *    $5 = /pub/ietf/uri/
 *    $6 = <undefined>
 *    $7 = <undefined>
 *    $8 = #Related
 *    $9 = Related
 * </pre>
 * where <undefined> indicates that the component is not present, as is the
 * case for the query component in the above example. Therefore, we can
 * determine the value of the five components as
 * <pre>
 *    scheme    = $2
 *    authority = $4
 *    path      = $5
 *    query     = $7
 *    fragment  = $9
 * </pre>
 *
 * The regular expression has been modified slightly to expose the
 * userInfo, domain, and port separately from the authority.
 * The modified version yields
 * <pre>
 *    $1 = http              scheme
 *    $2 = <undefined>       userInfo -\
 *    $3 = www.ics.uci.edu   domain     | authority
 *    $4 = <undefined>       port     -/
 *    $5 = /pub/ietf/uri/    path
 *    $6 = <undefined>       query without ?
 *    $7 = Related           fragment without #
 * </pre>

 * Creates a token that can be used in a DI Provider.
 *
 * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
 * runtime representation) such as when injecting an interface, callable type, array or
 * parameterized type.
 *
 * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
 * the `Injector`. This provides additional level of type safety.
 *
 * ```
 * interface MyInterface {...}
 * var myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
 * // myInterface is inferred to be MyInterface.
 * ```
 *
 * When creating an `InjectionToken`, you can optionally specify a factory function which returns
 * (possibly by creating) a default value of the parameterized type `T`. This sets up the
 * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
 * application's root injector. If the factory function, which takes zero arguments, needs to inject
 * dependencies, it can do so using the `inject` function. See below for an example.
 *
 * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
 * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
 * mentioned above, `'root'` is the default value for `providedIn`.

/**
 * A ReflectiveDependency injection container used for instantiating objects and resolving
 * dependencies.
 *
 * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
 * constructor dependencies.
 *
 * In typical use, application code asks for the dependencies in the constructor and they are
 * resolved by the `Injector`.
 *
 * @usageNotes
 * ### Example
 *
 * The following example creates an `Injector` configured to create `Engine` and `Car`.
 *
 * ```typescript
 * @Injectable()
 * class Engine {
 * }
 *
 * @Injectable()
 * class Car {
 *   constructor(public engine:Engine) {}
 * }
 *
 * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
 * var car = injector.get(Car);
 * expect(car instanceof Car).toBe(true);
 * expect(car.engine instanceof Engine).toBe(true);
 * ```
 *
 * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
 * resolve all of the object's dependencies automatically.
 *
 * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.
 * @publicApi

 * A pattern that recognizes a commonly useful subset of URLs that are safe.

 * Soy's EscapingConventions):
 * (1) Either an allowed protocol (http, https, mailto or ftp).
 * (2) or no protocol.  A protocol must be followed by a colon. The below

 *     A colon after a hash (#) must be in the fragment.
 *     Otherwise, a colon after a (?) must be in a query.
 *     Otherwise, a colon after a single solidus (/) must be in a path.
 *     Otherwise, a colon after a double solidus (//) must be in the authority
 *     (before port).
 *
 * The pattern disallows &, used in HTML entity declarations before
 * one of the characters in [/?#]. This disallows HTML entities used in the
 * protocol name, which should never happen, e.g. "h&#116;tp" for "http".
 * It also disallows HTML entities in the first path part of a relative path,
 * e.g. "foo&lt;bar/baz".  Our existing escaping functions should not produce

/**
 * Applies the given multi styling (styles or classes) values to the context.
 *
 * The styling algorithm code that applies multi-level styling (things like `[style]` and `[class]`
 * values) resides here.
 *
 * Because this function understands that multiple directives may all write to the `[style]` and
 * `[class]` bindings (through host bindings), it relies of each directive applying its binding
 * value in order. This means that a directive like `classADirective` will always fire before
 * `classBDirective` and therefore its styling values (classes and styles) will always be evaluated
 * in the same order. Because of this consistent ordering, the first directive has a higher priority
 * than the second one. It is with this prioritzation mechanism that the styling algorithm knows how
 * to merge and apply redudant styling properties.
 *
 * The function itself applies the key/value entries (or an array of keys) to
 * the context in the following steps.
 *
 * STEP 1:
 *    First check to see what properties are already set and in use by another directive in the
 *    context (e.g. `ngClass` set the `width` value and `[style.width]="w"` in a directive is
 *    attempting to set it as well).
 *
 * STEP 2:
 *    All remaining properties (that were not set prior to this directive) are now updated in
 *    the context. Any new properties are inserted exactly at their spot in the context and any
 *    previously set properties are shifted to exactly where the cursor sits while iterating over
 *    the context. The end result is a balanced context that includes the exact ordering of the
 *    styling properties/values for the provided input from the directive.
 *
 * STEP 3:
 *    Any unmatched properties in the context that belong to the directive are set to null
 *
 * Once the updating phase is done, then the algorithm will decide whether or not to flag the
 * follow-up directives (the directives that will pass in their styling values) depending on if
 * the "shape" of the multi-value map has changed (either if any keys are removed or added or
 * if there are any new `null` values). If any follow-up directives are flagged as dirty then the
 * algorithm will run again for them. Otherwise if the shape did not change then any follow-up
 * directives will not run (so long as their binding values stay the same).
 *
 * @returns the total amount of new slots that were allocated into the context due to new styling
 *          properties that were detected.

 * This function is shared between bindings that are assigned immediately
 * (via `updateBindingData`) and at a deferred stage. When called, it will
 * figure out exactly where to place the binding data in the context.
 *
 * It is needed because it will either update or insert a styling property
 * into the context at the correct spot.
 *
 * When called, one of two things will happen:
 *
 * 1) If the property already exists in the context then it will just add
 *    the provided `bindingValue` to the end of the binding sources region
 *    for that particular property.
 *
 *    - If the binding value is a number then it will be added as a new
 *      binding index source next to the other binding sources for the property.
 *
 *    - Otherwise, if the binding value is a string/boolean/null type then it will
 *      replace the default value for the property if the default value is `null`.
 *
 * 2) If the property does not exist then it will be inserted into the context.
 *    The styling context relies on all properties being stored in alphabetical
 *    order, so it knows exactly where to store it.
 *
 *    When inserted, a default `null` value is created for the property which exists
 *    as the default value for the binding. If the bindingValue property is inserted
 *    and it is either a string, number or null value then that will replace the default
 *    value.
 *
 * Note that this function is also used for map-based styling bindings. They are treated
 * much the same as prop-based bindings, but, because they do not have a property value
 * (since it's a map), all map-based entries are stored in an already populated area of
 * the context at the top (which is reserved for map-based entries).

/**
 * --------
 *
 * This file contains the algorithm logic for applying map-based bindings
 * such as `[style]` and `[class]`.
 *
 * --------
 */
/**
 * Used to apply styling values presently within any map-based bindings on an element.
 *
 * Angular supports map-based styling bindings which can be applied via the
 * `[style]` and `[class]` bindings which can be placed on any HTML element.
 * These bindings can work independently, together or alongside prop-based
 * styling bindings (e.g. `<div [style]="x" [style.width]="w">`).
 *
 * If a map-based styling binding is detected by the compiler, the following
 * AOT code is produced:
 *
 * ```typescript
 * styleMap(ctx.styles); // styles = {key:value}
 * classMap(ctx.classes); // classes = {key:value}|string
 * ```
 *
 * If and when either of the instructions above are evaluated, then the code
 * present in this file is included into the bundle. The mechanism used, to
 * activate support for map-based bindings at runtime is possible via the
 * `activeStylingMapFeature` function (which is also present in this file).
 *
 * # The Algorithm
 * Whenever a map-based binding updates (which is when the identity of the
 * map-value changes) then the map is iterated over and a `LStylingMap` array
 * is produced. The `LStylingMap` instance is stored in the binding location
 * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`
 * instruction were called. Once the binding changes, then the internal `bitMask`
 * value is marked as dirty.
 *
 * Styling values are applied once CD exits the element (which happens when
 * the `select(n)` instruction is called or the template function exits). When
 * this occurs, all prop-based bindings are applied. If a map-based binding is
 * present then a special flushing function (called a sync function) is made
 * available and it will be called each time a styling property is flushed.
 *
 * The flushing algorithm is designed to apply styling for a property (which is
 * a CSS property or a className value) one by one. If map-based bindings
 * are present, then the flushing algorithm will keep calling the maps styling
 * sync function each time a property is visited. This way, the flushing
 * behavior of map-based bindings will always be at the same property level
 * as the current prop-based property being iterated over (because everything
 * is alphabetically sorted).
 *
 * Let's imagine we have the following HTML template code:
 *
 * ```html
 * <div [style]="{width:'100px', height:'200px', 'z-index':'10'}"
 *      [style.width.px]="200">...</div>
 * ```
 *
 * When CD occurs, both the `[style]` and `[style.width]` bindings
 * are evaluated. Then when the styles are flushed on screen, the
 * following operations happen:
 *
 * 1. `[style.width]` is attempted to be written to the element.
 *
 * 2.  Once that happens, the algorithm instructs the map-based
 *     entries (`[style]` in this case) to "catch up" and apply
 *     all values up to the `width` value. When this happens the
 *     `height` value is applied to the element (since it is
 *     alphabetically situated before the `width` property).
 *
 * 3. Since there are no more prop-based entries anymore, the
 *    loop exits and then, just before the flushing ends, it
 *    instructs all map-based bindings to "finish up" applying
 *    their values.
 *
 * 4. The only remaining value within the map-based entries is
 *    the `z-index` value (`width` got skipped because it was
 *    successfully applied via the prop-based `[style.width]`
 *    binding). Since all map-based entries are told to "finish up",
 *    the `z-index` value is iterated over and it is then applied
 *    to the element.
 *
 * The most important thing to take note of here is that prop-based
 * bindings are evaluated in order alongside map-based bindings.
 * This allows all styling across an element to be applied in O(n)
 * time (a similar algorithm is that of the array merge algorithm
 * in merge sort).

 * Inserting a view without projection or containers at top level is simple. Just iterate over the
 * root nodes of the View, and for each node perform the `action`.
 *
 * Things get more complicated with containers and projections. That is because coming across:
 * - Container: implies that we have to insert/remove/destroy the views of that container as well
 *              which in turn can have their own Containers at the View roots.
 * - Projection: implies that we have to insert/remove/destroy the nodes of the projection. The
 *               complication is that the nodes we are projecting can themselves have Containers
 *               or other Projections.
 *
 * As you can see this is a very recursive problem. While the recursive implementation is not the
 * most efficient one, trying to unroll the nodes non-recursively results in very complex code that
 * is very hard (to maintain). We are sacrificing a bit of performance for readability using a
 * recursive implementation.

     * check every five seconds.

     * If we did not have this check then the insertion of `b` would:
     *   1) evict first `a`
     *   2) insert `b` at `0` index.
     *   3) leave `a` at index `1` as is. <-- this is wrong!
     *   3) reinsert `a` at index 2. <-- this is wrong!
     *
     * The correct behavior is:
     *   1) evict first `a`
     *   2) insert `b` at `0` index.
     *   3) reinsert `a` at index 1.
     *   3) move `a` at from `1` to `2`.
     *
     *
     * Double check that we have not evicted a duplicate item. We need to check if the item type may
     * have already been removed:
     * The insertion of b will evict the first 'a'. If we don't reinsert it now it will be reinserted
     * at the end. Which will show up as the two 'a's switching position. This is incorrect, since a
     * better way to think of it is as insert of 'b' rather then switch 'a' with 'b' and then add 'a'
     * at the end.

/**
 * Base class for Angular Views, provides change detection functionality.
 * A change-detection tree collects all views that are to be checked for changes.
 * Use the methods to add and remove views from the tree, initiate change-detection,
 * and explicitly mark views as _dirty_, meaning that they have changed and need to be rerendered.
 *
 * @usageNotes
 *
 * The following examples demonstrate how to modify default change-detection behavior
 * to perform explicit detection when needed.
 *
 * ### Use `markForCheck()` with `CheckOnce` strategy
 *
 * The following example sets the `OnPush` change-detection strategy for a component
 * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
 * after an interval. See [live demo](http://plnkr.co/edit/GC512b?p=preview).
 *
 * <code-example path="core/ts/change_detect/change-detection.ts"
 * region="mark-for-check"></code-example>
 *
 * ### Detach change detector to limit how often check occurs
 *
 * The following example defines a component with a large list of read-only data
 * that is expected to change constantly, many times per second.
 * To improve performance, we want to check and update the list
 * less often than the changes actually occur. To do that, we detach
 * the component's change detector and perform an explicit local check every five seconds.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
 *
 *
 * ### Reattaching a detached component
 *
 * The following example creates a component displaying live data.
 * The component detaches its change detector from the main change detector tree
 * when the `live` property is set to false, and reattaches it when the property
 * becomes true.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts" region="reattach"></code-example>

// This function calls the ngAfterContentCheck, ngAfterContentInit,
// ngAfterViewCheck, and ngAfterViewInit lifecycle hooks (depending on the node
// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are
// called during a pre-order traversal of the view tree (that is calling the
// parent hooks before the child hooks) these events are sent in using a
// post-order traversal of the tree (children before parents). This changes the
// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
// expected nodeIndex which a ngOnInit should be called. When sending
// ngAfterContentInit and ngAfterViewInit it is the expected count of
// ngAfterContentInit or ngAfterViewInit methods that have been called. This
// ensure that despite being called recursively or after picking up after an
// exception, the ngAfterContentInit or ngAfterViewInit will be called on the
// correct nodes. Consider for example, the following (where E is an element
// and D is a directive)
//  Tree:       pre-order index  post-order index
//    E1        0                6
//      E2      1                1
//       D3     2                0
//      E4      3                5
//       E5     4                4
//        E6    5                2
//        E7    6                3
// As can be seen, the post-order index has an unclear relationship to the
// pre-order index (postOrderIndex === preOrderIndex - parentCount +
// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
// are stable (will be the same for the same view regardless of exceptions or
// recursion) we just need to count them which will roughly correspond to the
// post-order index (it skips elements and directives that do not have
// lifecycle hooks).
//
// For example, if an exception is raised in the E6.onAfterViewInit() the
// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
// not have their ngAfterViewInit() called but, starting with E7, the rest of
// the view will begin getting ngAfterViewInit() called until a check and
// pass is complete.
//
// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
// When the recursion returns the initIndex will be 7 so E1 is skipped as it
// has already been called in the recursively called checkAnUpdateView().

/**
 * A reference to an Angular application running on a page.
 *
 * @usageNotes
 *
 * {@a is-stable-examples}
 * ### isStable examples and caveats
 *
 * Note two important points about `isStable`, demonstrated in the examples below:
 * - the application will never be stable if you start any kind
 * of recurrent asynchronous task when the application starts
 * (for example for a polling process, started with a `setInterval`, a `setTimeout`
 * or using RxJS operators like `interval`);
 * - the `isStable` Observable runs outside of the Angular zone.
 *
 * Let's imagine that you start a recurrent task
 * (here incrementing a counter, using RxJS `interval`),
 * and at the same time subscribe to `isStable`.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *      filter(stable => stable)
 *   ).subscribe(() => console.log('App is stable now');
 *   interval(1000).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, `isStable` will never emit `true`,
 * and the trace "App is stable now" will never get logged.
 *
 * If you want to execute something when the app is stable,
 * you have to wait for the application to be stable
 * before starting your polling process.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     tap(stable => console.log('App is stable now')),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, the trace "App is stable now" will be logged
 * and then the counter starts incrementing every second.
 *
 * Note also that this Observable runs outside of the Angular zone,
 * which means that the code in the subscription
 * to this Observable will not trigger the change detection.
 *
 * Let's imagine that instead of logging the counter value,
 * you update a field of your component
 * and display it in its template.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => this.value = counter);
 * }
 * ```
 * As the `isStable` Observable runs outside the zone,
 * the `value` field will be updated properly,
 * but the template will not be refreshed!
 *
 * You'll have to manually trigger the change detection to update the template.
 *
 * ```
 * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => {
 *     this.value = counter;
 *     cd.detectChanges();
 *   });
 * }
 * ```
 *
 * Or make the subscription callback run inside the zone.
 *
 * ```
 * constructor(appRef: ApplicationRef, zone: NgZone) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => zone.run(() => this.value = counter));
 * }
 * ```

 * MediaObserver enables applications to listen for 1..n mediaQuery activations and to determine

 *
 * Since a breakpoint change will first deactivate 1...n mediaQueries and then possibly activate
 * 1..n mediaQueries, the MediaObserver will debounce notifications and report ALL *activations*
 * in 1 event notification. The reported activations will be sorted in descending priority order.
 *
 * This class uses the BreakPoint Registry to inject alias information into the raw MediaChange
 * notification. For custom mediaQuery notifications, alias information will not be injected and
 * those fields will be ''.
 *
 * Note: Developers should note that only mediaChange activations (not de-activations)
 *       are announced by the MediaObserver.

 * ```ts
 * const firstNameControl = new FormControl();

 * @description
 * The `ControlValueAccessor` for writing select control values and listening to select control
 * changes. The value accessor is used by the `FormControlDirective`, `FormControlName`, and
 * `NgModel` directives.
 *
 * @usageNotes
 *
 * ### Using select controls in a reactive form
 *
 * The following examples show how to use a select control in a reactive form.
 *
 * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
 *
 * ### Using select controls in a template-driven form
 *
 * To use a select in a template-driven form, simply add an `ngModel` and a `name`
 * attribute to the main `<select>` tag.
 *
 * {@example forms/ts/selectControl/select_control_example.ts region='Component'}
 *
 * ### Customizing option selection
 *
 * Angular uses object identity to select option. It's possible for the identities of items
 * to change while the data does not. This can happen, for example, if the items are produced
 * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the
 * second response will produce objects with different identities.
 *
 * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
 * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
 * If `compareWith` is given, Angular selects option by the return value of the function.
 *
 * ```ts
 * const selectedCountriesControl = new FormControl();
 * ```
 *
 * ```
 * <select [compareWith]="compareFn"  [formControl]="selectedCountriesControl">
 *     <option *ngFor="let country of countries" [ngValue]="country">
 *         {{country.name}}
 *     </option>
 * </select>
 *
 * compareFn(c1: Country, c2: Country): boolean {
 *     return c1 && c2 ? c1.id === c2.id : c1 === c2;
 * }
 * ```
 *
 * **Note:** We listen to the 'change' event because 'input' events aren't fired
 * for selects in Firefox and IE:
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350

 * ### Using a multi-select control
 *
 * The follow example shows you how to use a multi-select control with a reactive form.
 *
 * ```ts
 * const countryControl = new FormControl();
 * ```
 *
 * ```
 * <select multiple name="countries" [formControl]="countryControl">
 *   <option *ngFor="let country of countries" [ngValue]="country">
 *     {{ country.name }}
 *   </option>
 * </select>
 * ```
 *
 * ### Customizing option selection
 *
 * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
 * See the `SelectControlValueAccessor` for usage.

 * Tracks the value and validation status of an individual form control.
 *
 * This is one of the three fundamental building blocks of Angular forms, along with

 * user interactions and events.
 *
 * @see `AbstractControl`
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see [Usage Notes](#usage-notes)
 *
 * @usageNotes
 *
 * ### Initializing Form Controls
 *
 * Instantiate a `FormControl`, with an initial value.
 *
 * ```ts
 * const control = new FormControl('some value');
 * console.log(control.value);     // 'some value'
 *```
 *
 * The following example initializes the control with a form state object. The `value`
 * and `disabled` keys are required in this case.
 *
 * ```ts
 * const control = new FormControl({ value: 'n/a', disabled: true });
 * console.log(control.value);     // 'n/a'
 * console.log(control.status);    // 'DISABLED'
 * ```
 *
 * The following example initializes the control with a sync validator.
 *
 * ```ts
 * const control = new FormControl('', Validators.required);
 * console.log(control.value);      // ''
 * console.log(control.status);     // 'INVALID'
 * ```
 *
 * The following example initializes the control using an options object.
 *
 * ```ts
 * const control = new FormControl('', {
 *    validators: Validators.required,
 *    asyncValidators: myAsyncValidator
 * });
 * ```
 *
 * ### Configure the control to update on a blur event
 *
 * Set the `updateOn` option to `'blur'` to update on the blur `event`.
 *
 * ```ts
 * const control = new FormControl('', { updateOn: 'blur' });
 * ```
 *
 * ### Configure the control to update on a submit event
 *
 * Set the `updateOn` option to `'submit'` to update on a submit `event`.
 *
 * ```ts
 * const control = new FormControl('', { updateOn: 'submit' });
 * ```
 *
 * ### Reset the control back to an initial value
 *
 * You reset to a specific form state by passing through a standalone
 * value or a form state object that contains both a value and a disabled state
 * (these are the only two properties that cannot be calculated).
 *
 * ```ts
 * const control = new FormControl('Nancy');
 *
 * console.log(control.value); // 'Nancy'
 *
 * control.reset('Drew');
 *
 * console.log(control.value); // 'Drew'
 * ```
 *
 * ### Reset the control back to an initial value and disabled
 *
 * ```
 * const control = new FormControl('Nancy');
 *
 * console.log(control.value); // 'Nancy'
 * console.log(control.status); // 'VALID'
 *
 * control.reset({ value: 'Drew', disabled: true });
 *
 * console.log(control.value); // 'Drew'
 * console.log(control.status); // 'DISABLED'
 * ```

/**
 * Tracks the value and validity state of a group of `FormControl` instances.
 *
 * A `FormGroup` aggregates the values of each child `FormControl` into one object,
 * with each control name as the key.  It calculates its status by reducing the status values
 * of its children. For example, if one of the controls in a group is invalid, the entire
 * group becomes invalid.
 *
 * `FormGroup` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormArray`.
 *
 * When instantiating a `FormGroup`, pass in a collection of child controls as the first
 * argument. The key for each child registers the name for the control.
 *
 * @usageNotes
 *
 * ### Create a form group with 2 controls
 *
 * ```
 * const form = new FormGroup({
 *   first: new FormControl('Nancy', Validators.minLength(2)),
 *   last: new FormControl('Drew'),
 * });
 *
 * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}
 * console.log(form.status);  // 'VALID'
 * ```
 *
 * ### Create a form group with a group-level validator
 *
 * You include group-level validators as the second arg, or group-level async
 * validators as the third arg. These come in handy when you want to perform validation
 * that considers the value of more than one child control.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('', Validators.minLength(2)),
 *   passwordConfirm: new FormControl('', Validators.minLength(2)),
 * }, passwordMatchValidator);
 *
 *
 * function passwordMatchValidator(g: FormGroup) {
 *    return g.get('password').value === g.get('passwordConfirm').value
 *       ? null : {'mismatch': true};
 * }
 * ```
 *
 * Like `FormControl` instances, you choose to pass in
 * validators and async validators as part of an options object.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('')
 *   passwordConfirm: new FormControl('')
 * }, { validators: passwordMatchValidator, asyncValidators: otherValidator });
 * ```
 *
 * ### Set the updateOn property for all controls in a form group
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * group level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const c = new FormGroup({
 *   one: new FormControl()
 * }, { updateOn: 'blur' });
 * ```

/**
 * Tracks the value and validity state of an array of `FormControl`,
 * `FormGroup` or `FormArray` instances.
 *
 * A `FormArray` aggregates the values of each child `FormControl` into an array.
 * It calculates its status by reducing the status values of its children. For example, if one of
 * the controls in a `FormArray` is invalid, the entire array becomes invalid.
 *
 * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormGroup`.
 *
 * @usageNotes
 *
 * ### Create an array of form controls
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * ### Create a form array with array-level validators
 *
 * You include array-level validators and async validators. These come in handy
 * when you want to perform validation that considers the value of more than one child
 * control.
 *
 * The two types of validators are passed in separately as the second and third arg
 * respectively, or together as part of an options object.
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy'),
 *   new FormControl('Drew')
 * ], {validators: myValidator, asyncValidators: myAsyncValidator});
 * ```
 *
  * ### Set the updateOn property for all controls in a form array
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * array level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const arr = new FormArray([
 *    new FormControl()
 * ], {updateOn: 'blur'});
 * ```
 *
 * ### Adding or removing controls from a form array
 *
 * To change the controls in the array, use the `push`, `insert`, `removeAt` or `clear` methods
 * in `FormArray` itself. These methods ensure the controls are properly tracked in the
 * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate
 * the `FormArray` directly, as that result in strange and unexpected behavior such
 * as broken change detection.

/**
 * @description
 * Creates a top-level `FormGroup` instance and binds it to a form
 * to track aggregate form value and validation status.
 *
 * As soon as you import the `FormsModule`, this directive becomes active by default on
 * all `<form>` tags.  You don't need to add a special selector.
 *
 * You optionally export the directive into a local template variable using `ngForm` as the key
 * (ex: `#myForm="ngForm"`). This is optional, but useful.  Many properties from the underlying
 * `FormGroup` instance are duplicated on the directive itself, so a reference to it
 * gives you access to the aggregate value and validity status of the form, as well as
 * user interaction properties like `dirty` and `touched`.
 *
 * To register child controls with the form, use `NgModel` with a `name`
 * attribute. You may use `NgModelGroup` to create sub-groups within the form.
 *
 * If necessary, listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event emits the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * To import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, add the `ngNoForm` and the `<form>`
 * tags won't create an `NgForm` directive. In reactive forms, using `ngNoForm` is
 * unnecessary because the `<form>` tags are inert. In that case, you would
 * refrain from using the `formGroup` directive.
 *
 * @usageNotes
 *
 * ### Migrating from deprecated ngForm selector
 *
 * Support for using `ngForm` element selector has been deprecated in Angular v6 and will be removed
 * in Angular v9.
 *
 * This has been deprecated to keep selectors consistent with other core Angular selectors,
 * as element selectors are typically written in kebab-case.
 *
 * Now deprecated:
 * ```html
 * <ngForm #myForm="ngForm">
 * ```
 *
 * After:
 * ```html
 * <ng-form #myForm="ngForm">
 * ```
 *
 * ### Listening for form submission
 *
 * The following example shows how to capture the form values from the "ngSubmit" event.
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Setting the update options
 *
 * The following example shows you how to change the "updateOn" option from its default using
 * ngFormOptions.
 *
 * ```html
 * <form [ngFormOptions]="{updateOn: 'blur'}">
 *    <input name="one" ngModel>  <!-- this ngModel will update on blur -->
 * </form>
 * ```

/**
 * @description
 * Creates a `FormControl` instance from a domain model and binds it
 * to a form control element.
 *
 * The `FormControl` instance tracks the value, user interaction, and
 * validation status of the control and keeps the view synced with the model. If used
 * within a parent form, the directive also registers itself with the form as a child
 * control.
 *
 * This directive is used by itself or as part of a larger form. Use the
 * `ngModel` selector to activate it.
 *
 * It accepts a domain model as an optional `Input`. If you have a one-way binding
 * to `ngModel` with `[]` syntax, changing the value of the domain model in the component
 * class sets the value in the view. If you have a two-way binding with `[()]` syntax
 * (also known as 'banana-box syntax'), the value in the UI always syncs back to
 * the domain model in your class.
 *
 * To inspect the properties of the associated `FormControl` (like validity state),
 * export the directive into a local template variable using `ngModel` as the key (ex: `#myVar="ngModel"`).
 * You then access the control using the directive's `control` property,
 * but most properties used (like `valid` and `dirty`) fall through to the control anyway for direct access.
 * See a full list of properties directly available in `AbstractControlDirective`.
 *
 * @see `RadioControlValueAccessor`
 * @see `SelectControlValueAccessor`
 *
 * @usageNotes
 *
 * ### Using ngModel on a standalone control
 *
 * The following examples show a simple standalone control using `ngModel`:
 *
 * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}
 *
 * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute
 * so that the control can be registered with the parent form under that name.
 *
 * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,
 * as the parent form syncs the value for you. You access its properties by exporting it into a
 * local template variable using `ngForm` such as (`#f="ngForm"`). Use the variable where
 * needed on form submission.
 *
 * If you do need to populate initial values into your form, using a one-way binding for
 * `ngModel` tends to be sufficient as long as you use the exported form's value rather
 * than the domain model's value on submit.
 *
 * ### Using ngModel within a form
 *
 * The following example shows controls using `ngModel` within a form:
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Using a standalone ngModel within a group
 *
 * The following example shows you how to use a standalone ngModel control
 * within a form. This controls the display of the form, but doesn't contain form data.
 *
 * ```html
 * <form>
 *   <input name="login" ngModel placeholder="Login">
 *   <input type="checkbox" ngModel [ngModelOptions]="{standalone: true}"> Show more options?
 * </form>
 * <!-- form value: {login: ''} -->
 * ```
 *
 * ### Setting the ngModel name attribute through options
 *
 * The following example shows you an alternate way to set the name attribute. The name attribute is used
 * within a custom form component, and the name `@Input` property serves a different purpose.
 *
 * ```html
 * <form>
 *   <my-person-control name="Nancy" ngModel [ngModelOptions]="{name: 'user'}">
 *   </my-person-control>
 * </form>
 * <!-- form value: {user: ''} -->
 * ```

 * @description
 * * Syncs a standalone `FormControl` instance to a form control element.
 *
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see `FormControl`
 * @see `AbstractControl`
 *
 * @usageNotes
 *
 * ### Registering a single form control
 *
 * The following examples shows how to register a standalone control and set its value.
 *
 * {@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}
 *
 * ### Use with ngModel
 *
 * Support for using the `ngModel` input property and `ngModelChange` event with reactive
 * form directives has been deprecated in Angular v6 and will be removed in Angular v7.
 *
 * Now deprecated:
 *
 * ```html
 * <input [formControl]="control" [(ngModel)]="value">
 * ```
 *
 * ```ts
 * this.value = 'some value';
 * ```
 *
 * This has been deprecated for a few reasons. First, developers have found this pattern
 * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's
 * an input/output property named `ngModel` on the reactive form directive that simply
 * approximates (some of) its behavior. Specifically, it allows getting/setting the value
 * and intercepting value events. However, some of `ngModel`'s other features - like
 * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,
 * which has understandably caused some confusion.
 *
 * In addition, this pattern mixes template-driven and reactive forms strategies, which
 * we generally don't recommend because it doesn't take advantage of the full benefits of
 * either strategy. Setting the value in the template violates the template-agnostic
 * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in
 * the class removes the convenience of defining forms in the template.
 *
 * To update your code before v7, you'll want to decide whether to stick with reactive form
 * directives (and get/set values using reactive forms patterns) or switch over to
 * template-driven directives.
 *
 * After (choice 1 - use reactive forms):
 *
 * ```html
 * <input [formControl]="control">
 * ```
 *
 * ```ts
 * this.control.setValue('some value');
 * ```
 *
 * After (choice 2 - use template-driven forms):
 *
 * ```html
 * <input [(ngModel)]="value">
 * ```
 *
 * ```ts
 * this.value = 'some value';
 * ```
 *
 * By default, when you use this pattern, you will see a deprecation warning once in dev
 * mode. You can choose to silence this warning by providing a config for
 * `ReactiveFormsModule` at import time:
 *
 * ```ts
 * imports: [
 *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});
 * ]
 * ```
 *
 * Alternatively, you can choose to surface a separate warning for each instance of this
 * pattern with a config value of `"always"`. This may help to track down where in the code
 * the pattern is being used as the code is being updated.

/**
 * @description
 * Syncs a `FormControl` in an existing `FormGroup` to a form control
 * element by name.
 *
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see `FormControl`
 * @see `AbstractControl`
 *
 * @usageNotes
 *
 * ### Register `FormControl` within a group
 *
 * The following example shows how to register multiple form controls within a form group
 * and set their value.
 *
 * {@example forms/ts/simpleFormGroup/simple_form_group_example.ts region='Component'}
 *
 * To see `formControlName` examples with different form control types, see:
 *
 * * Radio buttons: `RadioControlValueAccessor`
 * * Selects: `SelectControlValueAccessor`
 *
 * ### Use with ngModel
 *
 * Support for using the `ngModel` input property and `ngModelChange` event with reactive
 * form directives has been deprecated in Angular v6 and will be removed in Angular v7.
 *
 * Now deprecated:
 *
 * ```html
 * <form [formGroup]="form">
 *   <input formControlName="first" [(ngModel)]="value">
 * </form>
 * ```
 *
 * ```ts
 * this.value = 'some value';
 * ```
 *
 * This has been deprecated for a few reasons. First, developers have found this pattern
 * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's
 * an input/output property named `ngModel` on the reactive form directive that simply
 * approximates (some of) its behavior. Specifically, it allows getting/setting the value
 * and intercepting value events. However, some of `ngModel`'s other features - like
 * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,
 * which has understandably caused some confusion.
 *
 * In addition, this pattern mixes template-driven and reactive forms strategies, which
 * we generally don't recommend because it doesn't take advantage of the full benefits of
 * either strategy. Setting the value in the template violates the template-agnostic
 * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in
 * the class removes the convenience of defining forms in the template.
 *
 * To update your code before v7, you'll want to decide whether to stick with reactive form
 * directives (and get/set values using reactive forms patterns) or switch over to
 * template-driven directives.
 *
 * After (choice 1 - use reactive forms):
 *
 * ```html
 * <form [formGroup]="form">
 *   <input formControlName="first">
 * </form>
 * ```
 *
 * ```ts
 * this.form.get('first').setValue('some value');
 * ```
 *
 * After (choice 2 - use template-driven forms):
 *
 * ```html
 * <input [(ngModel)]="value">
 * ```
 *
 * ```ts
 * this.value = 'some value';
 * ```
 *
 * By default, when you use this pattern, you will see a deprecation warning once in dev
 * mode. You can choose to silence this warning by providing a config for
 * `ReactiveFormsModule` at import time:
 *
 * ```ts
 * imports: [
 *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'})
 * ]
 * ```
 *
 * Alternatively, you can choose to surface a separate warning for each instance of this
 * pattern with a config value of `"always"`. This may help to track down where in the code
 * the pattern is being used as the code is being updated.

 * destination state's style definition, in situations where we are moving from `void`'s styles to
 * `collapsed` this acts a noop since no style values change.
 *
 * In the case where angular's animation state is out of sync with the expansion panel's state, the
 * expansion panel being `expanded` and angular animations being `void`, the animation from the
 * `expanded`'s effective styles (though in a `void` animation state) to the collapsed state will

 * Component to display an icon. It can be used in the following ways:
 *
 * - Specify the svgIcon input to load an SVG icon from a URL previously registered with the
 *   addSvgIcon, addSvgIconInNamespace, addSvgIconSet, or addSvgIconSetInNamespace methods of
 *   MatIconRegistry. If the svgIcon value contains a colon it is assumed to be in the format
 *   "[namespace]:[name]", if not the value will be the name of an icon in the default namespace.
 *   Examples:
 *     `<mat-icon svgIcon="left-arrow"></mat-icon>
 *     <mat-icon svgIcon="animals:cat"></mat-icon>`
 *
 * - Use a font ligature as an icon by putting the ligature text in the content of the `<mat-icon>`
 *   component. By default the Material icons font is used as described at
 *   http://google.github.io/material-design-icons/#icon-font-for-the-web. You can specify an
 *   alternate font by setting the fontSet input to either the CSS class to apply to use the
 *   desired font, or to an alias previously registered with MatIconRegistry.registerFontClassAlias.
 *   Examples:
 *     `<mat-icon>home</mat-icon>
 *     <mat-icon fontSet="myfont">sun</mat-icon>`
 *
 * - Specify a font glyph to be included via CSS rules by setting the fontSet input to specify the
 *   font, and the fontIcon input to specify the icon. Typically the fontIcon will specify a
 *   CSS class which causes the glyph to be displayed via a :before selector, as in
 *   https://fortawesome.github.io/Font-Awesome/examples/
 *   Example:
 *     `<mat-icon fontSet="fa" fontIcon="alarm"></mat-icon>`

/**
 * DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
 * values to be safe to use in the different DOM contexts.
 *
 * For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
 * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
 * the website.
 *
 * In specific situations, it might be necessary to disable sanitization, for example if the
 * application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
 * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
 * methods, and then binding to that value from the template.
 *
 * These situations should be very rare, and extraordinary care must be taken to avoid creating a
 * Cross Site Scripting (XSS) security bug!
 *
 * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
 * close as possible to the source of the value, to make it easy to verify no security bug is
 * created by its use.
 *
 * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
 * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
 * code. The sanitizer leaves safe values intact.
 *
 * @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
 * sanitization for the value passed in. Carefully check and audit all values and code paths going
 * into this call. Make sure any user data is appropriately escaped for this security context.
 * For more detail, see the [Security Guide](http://g.co/ng/security).
