/**
 * This class should not be used directly by an application developer. Instead, use
 * {\@link Location}.
 *
 * `PlatformLocation` encapsulates all calls to DOM apis, which allows the Router to be platform
 * 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.

 * Applications should use the `Router` or `Location` services to

 *
 * For instance, `HashLocationStrategy` produces URLs like
 * <code class="no-auto-link">http://example.com#/foo</code>,

 *
 * 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` 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

/**
 * 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
 * true.</div></ng-template>
 * ```
 *
 * Form with an "else" block:
 *
 * ```
 * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Shorthand form with "then" and "else" blocks:
 *
 * ```
 * <div *ngIf="condition; then thenBlock else elseBlock"></div>
 * <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>

 * Formats a date according to locale rules.
 *
 * Where:
 * - `expression` is a date object or a number (milliseconds since UTC epoch) or an ISO string
 * (https://www.w3.org/TR/NOTE-datetime).
 * - `format` indicates which date/time components to include. The format can be predefined as
 *   shown below or custom as shown in the table.
 *   - `'medium'`: equivalent to `'yMMMdjms'` (e.g. `Sep 3, 2010, 12:05:08 PM` for `en-US`)
 *   - `'short'`: equivalent to `'yMdjm'` (e.g. `9/3/2010, 12:05 PM` for `en-US`)
 *   - `'fullDate'`: equivalent to `'yMMMMEEEEd'` (e.g. `Friday, September 3, 2010` for `en-US`)
 *   - `'longDate'`: equivalent to `'yMMMMd'` (e.g. `September 3, 2010` for `en-US`)
 *   - `'mediumDate'`: equivalent to `'yMMMd'` (e.g. `Sep 3, 2010` for `en-US`)
 *   - `'shortDate'`: equivalent to `'yMd'` (e.g. `9/3/2010` for `en-US`)
 *   - `'mediumTime'`: equivalent to `'jms'` (e.g. `12:05:08 PM` for `en-US`)
 *   - `'shortTime'`: equivalent to `'jm'` (e.g. `12:05 PM` for `en-US`)

 * 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.

 *
 * Unwraps a value from an asynchronous primitive.
 *
 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
 * potential memory leaks.
 *
 * \@usageNotes
 *
 * ### Examples
 *
 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
 * promise.
 *
 * {\@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
 *
 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
 * to the view. The Observable continuously updates the view with the current time.
 *

 *
 * 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();
 * }
 * ```

 * \@ngModule CommonModule
 * \@description
 *
 * Creates a new `Array` or `String` containing a subset (slice) of the elements.
 *
 * \@usageNotes
 *
 * All behavior is based on the expected behavior of the JavaScript API `Array.prototype.slice()`
 * and `String.prototype.slice()`.
 *
 * When operating on an `Array`, the returned `Array` is always a copy even when all
 * the elements are being returned.
 *
 * When operating on a blank value, the pipe returns the blank value.
 *
 * ### List Example
 *
 * This `ngFor` example:
 *
 * {\@example common/pipes/ts/slice_pipe.ts region='SlicePipe_list'}
 *
 * produces the following:
 *
 * ```html
 * <li>b</li>
 * <li>c</li>
 * ```
 *
 * ### String Examples
 *
 * {\@example common/pipes/ts/slice_pipe.ts region='SlicePipe_string'}
