    // All japanese encodings are based on JIS X set of standards:
    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
    //              Has several variations in 1978, 1983, 1990 and 1997.
    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
    //              2 planes, first is superset of 0208, second - revised 0212.
    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)

    // Byte encodings are:
    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
    //               0x00-0x7F       - lower part of 0201
    //               0x8E, 0xA1-0xDF - upper part of 0201
    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
    //               Used as-is in ISO2022 family.
    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
    //                0201-1976 Roman, 0208-1978, 0208-1983.
    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
    //
    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

 * A service that applications can use to interact with a browser's URL.
 *
 * Depending on the `LocationStrategy` used, `Location` persists
 * to the URL's path or the URL's hash segment.
 *
 * @usageNotes
 *
 * It's better to use the `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
 * true.</div></ng-template>
 * ```
 *
 * Form with an "else" block:
 *
 * ```

 * <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>
 *     </container-element>

 * If the VE is present (which is for older versions of Angular) then NgStyle will inject
 * the legacy diffing algorithm as a service and delegate all styling changes to that.
 *
 * If the VE is not present then NgStyle will normalize (through the injected service) and
 * then write all styling changes to the `[style]` binding directly (through a host binding).
 * Then Angular will notice the host binding change and treat the changes as styling
 * changes and apply them via the core styling instructions that exist within Angular.

 * 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();
 * }
 * ```

/**
 * 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`.

 * // TODO(matsko): add updateMask info
 *
 * This file contains all state-based logic for styling in Angular.
 *
 * Styling in Angular is evaluated with a series of styling-specific
 * template instructions which are called one after another each time
 * change detection occurs in Angular.
 *
 * Styling makes use of various temporary, state-based variables between
 * instructions so that it can better cache and optimize its values.
 * These values are usually populated and cleared when an element is
 * exited in change detection (once all the instructions are run for
 * that element).
 *
 * There are, however, situations where the state-based values
 * need to be stored and used at a later point. This ONLY occurs when
 * there are template-level as well as host-binding-level styling
 * instructions on the same element. The example below shows exactly
 * what could be:
 *
 * ```html
 * <!-- two sources of styling: the template and the directive -->
 * <div [style.width]="width" dir-that-sets-height></div>
 * ```
 *
 * If and when this situation occurs, the current styling state is
 * stored in a storage map value and then later accessed once the
 * host bindings are evaluated. Once styling for the current element
 * is over then the map entry will be cleared.
 *
 * To learn more about the algorithm see `TStylingContext`.

 * A pattern that recognizes a commonly useful subset of URLs that are safe.
 *
 * This regular expression matches a subset of URLs that will not cause script
 * execution if used in URL context within a HTML document. Specifically, this
 * regular expression matches if (comment from here on and regex copied from
 * 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
 *     allows that by allowing colons only after one of the characters [/?#].
 *     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
 * that. More importantly, it disallows masking of a colon,
 * e.g. "javascript&#58;...".
 *
 * This regular expression was taken from the Closure sanitization library.

 * It is needed because it will either update or insert a styling property
 * into the context at the correct spot.
 *

 *
 * 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.

 *
 *    - 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 `StylingMapArray` array
 * is produced. The `StylingMapArray` 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).

 *               or other Projections.
 *

/**
 * 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().

 * An injectable service for executing work inside or outside of the Angular zone.
 *
 * The most common use of this service is to optimize performance when starting a work consisting of
 * one or more asynchronous tasks that don't require UI updates or error handling to be handled by
 * Angular. Such tasks can be kicked off via {@link #runOutsideAngular} and if needed, these tasks
 * can reenter the Angular zone via {@link #run}.
 *
 * <!-- TODO: add/fix links to:
 *   - docs explaining zones and the use of zones in Angular and change-detection
 *   - link to runOutsideAngular/run (throughout this file!)

/**
 * 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));
 * }
 * ```

  /*
   * Attributes in the DOM are tricky:
   *
   * - there are the 8 basic get/set/has/removeAttribute{NS} methods
   *
   * - but many HTML attributes are also 'reflected' through IDL
   *   attributes which means that they can be queried and set through
   *   regular properties of the element.  There is just one attribute
   *   value, but two ways to get and set it.
   *
   * - Different HTML element types have different sets of reflected
     attributes.
   *
   * - attributes can also be queried and set through the .attributes
   *   property of an element.  This property behaves like an array of
   *   Attr objects.  The value property of each Attr is writeable, so
   *   this is a third way to read and write attributes.
   *
   * - for efficiency, we really want to store attributes in some kind
   *   of name->attr map.  But the attributes[] array is an array, not a
   *   map, which is kind of unnatural.
   *
   * - When using namespaces and prefixes, and mixing the NS methods
   *   with the non-NS methods, it is apparently actually possible for
   *   an attributes[] array to have more than one attribute with the
   *   same qualified name.  And certain methods must operate on only
   *   the first attribute with such a name.  So for these methods, an
   *   inefficient array-like data structure would be easier to
   *   implement.
   *
   * - The attributes[] array is live, not a snapshot, so changes to the
   *   attributes must be immediately visible through existing arrays.
   *
   * - When attributes are queried and set through IDL properties
   *   (instead of the get/setAttributes() method or the attributes[]
   *   array) they may be subject to type conversions, URL
   *   normalization, etc., so some extra processing is required in that
   *   case.
   *
   * - But access through IDL properties is probably the most common
   *   case, so we'd like that to be as fast as possible.
   *
   * - We can't just store attribute values in their parsed idl form,
   *   because setAttribute() has to return whatever string is passed to
   *   getAttribute even if it is not a legal, parseable value. So
   *   attribute values must be stored in unparsed string form.
   *
   * - We need to be able to send change notifications or mutation
   *   events of some sort to the renderer whenever an attribute value
   *   changes, regardless of the way in which it changes.
   *
   * - Some attributes, such as id and class affect other parts of the
   *   DOM API, like getElementById and getElementsByClassName and so
   *   for efficiency, we need to specially track changes to these
   *   special attributes.
   *
   * - Some attributes like class have different names (className) when
   *   reflected.
   *
   * - Attributes whose names begin with the string 'data-' are treated
     specially.
   *
   * - Reflected attributes that have a boolean type in IDL have special
   *   behavior: setting them to false (in IDL) is the same as removing
   *   them with removeAttribute()
   *
   * - numeric attributes (like HTMLElement.tabIndex) can have default
   *   values that must be returned by the idl getter even if the
   *   content attribute does not exist. (The default tabIndex value
   *   actually varies based on the type of the element, so that is a
   *   tricky one).
   *
   * See
   * http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#reflect
   * for rules on how attributes are reflected.

 * This file contains an implementation of the HTML parsing algorithm.
 * The algorithm and the implementation are complex because HTML
 * explicitly defines how the parser should behave for all possible
 * valid and invalid inputs.
 *
 * Usage:
 *
 * The file defines a single HTMLParser() function, which dom.js exposes
 * publicly as document.implementation.mozHTMLParser(). This is a
 * factory function, not a constructor.
 *
 * When you call document.implementation.mozHTMLParser(), it returns
 * an object that has parse() and document() methods. To parse HTML text,
 * pass the text (in one or more chunks) to the parse() method.  When
 * you've passed all the text (on the last chunk, or afterward) pass
 * true as the second argument to parse() to tell the parser that there
 * is no more coming. Call document() to get the document object that
 * the parser is parsing into.  You can call this at any time, before
 * or after calling parse().
 *
 * The first argument to mozHTMLParser is the absolute URL of the document.
 *
 * The second argument is optional and is for internal use only.  Pass an
 * element as the fragmentContext to do innerHTML parsing for the
 * element.  To do innerHTML parsing on a document, pass null. Otherwise,
 * omit the 2nd argument. See HTMLElement.innerHTML for an example.  Note
 * that if you pass a context element, the end() method will return an
 * unwrapped document instead of a wrapped one.
 *
 * Implementation details:
 *
 * This is a long file of almost 7000 lines. It is structured as one
 * big function nested within another big function.  The outer
 * function defines a bunch of constant data, utility functions
 * that use that data, and a couple of classes used by the parser.
 * The outer function also defines and returns the
 * inner function. This inner function is the HTMLParser factory
 * function that implements the parser and holds all the parser state
 * as local variables.  The HTMLParser function is quite big because
 * it defines many nested functions that use those local variables.
 *
 * There are three tightly coupled parser stages: a scanner, a
 * tokenizer and a tree builder. In a (possibly misguided) attempt at
 * efficiency, the stages are not implemented as separate classes:
 * everything shares state and is (mostly) implemented in imperative
 * (rather than OO) style.
 *
 * The stages of the parser work like this: When the client code calls
 * the parser's parse() method, the specified string is passed to
 * scanChars(). The scanner loops through that string and passes characters
 * (sometimes one at a time, sometimes in chunks) to the tokenizer stage.
 * The tokenizer groups the characters into tokens: tags, endtags, runs
 * of text, comments, doctype declarations, and the end-of-file (EOF)
 * token.  These tokens are then passed to the tree building stage via
 * the insertToken() function.  The tree building stage builds up the
 * document tree.
 *
 * The tokenizer stage is a finite state machine.  Each state is
 * implemented as a function with a name that ends in "_state".  The
 * initial state is data_state(). The current tokenizer state is stored
 * in the variable 'tokenizer'.  Most state functions expect a single
 * integer argument which represents a single UTF-16 codepoint.  Some
 * states want more characters and set a lookahead property on
 * themselves.  The scanChars() function in the scanner checks for this
 * lookahead property.  If it doesn't exist, then scanChars() just passes
 * the next input character to the current tokenizer state function.
 * Otherwise, scanChars() looks ahead (a given # of characters, or for a
 * matching string, or for a matching regexp) and passes a string of
 * characters to the current tokenizer state function.
 *
 * As a shortcut, certain states of the tokenizer use regular expressions
 * to look ahead in the scanner's input buffer for runs of text, simple
 * tags and attributes.  For well-formed input, these shortcuts skip a
 * lot of state transitions and speed things up a bit.
 *
 * When a tokenizer state function has consumed a complete token, it
 * emits that token, by calling insertToken(), or by calling a utility
 * function that itself calls insertToken().  These tokens are passed to
 * the tree building stage, which is also a state machine.  Like the
 * tokenizer, the tree building states are implemented as functions, and
 * these functions have names that end with _mode (because the HTML spec
 * refers to them as insertion modes). The current insertion mode is held
 * by the 'parser' variable.  Each insertion mode function takes up to 4
 * arguments.  The first is a token type, represented by the constants
 * TAG, ENDTAG, TEXT, COMMENT, DOCTYPE and EOF.  The second argument is
 * the value of the token: the text or comment data, or tagname or
 * doctype.  For tags, the 3rd argument is an array of attributes.  For
 * DOCTYPES it is the optional public id.  For tags, the 4th argument is
 * true if the tag is self-closing. For doctypes, the 4th argument is the
 * optional system id.
 *
 * Search for "***" to find the major sub-divisions in the code.

   *
   * After mechanical conversion, it was further converted from

   * faithful rendering of the HTML tokenization spec in
   * JavaScript.
   *
   * It is not a goal of this tokenizer to detect or report
   * parse errors.
   *
   * XXX The tokenizer is supposed to work with straight UTF32
   * codepoints. But I don't think it has any dependencies on
   * any character outside of the BMP so I think it is safe to
   * pass it UTF16 characters. I don't think it will ever change
   * state in the middle of a surrogate pair.
   */

  /*
   * Each state is represented by a function.  For most states, the
   * scanner simply passes the next character (as an integer
   * codepoint) to the current state function and automatically
   * consumes the character.  If the state function can't process
   * the character it can call pushback() to push it back to the
   * scanner.
   *
   * Some states require lookahead, though.  If a state function has
   * a lookahead property, then it is invoked differently.  In this
   * case, the scanner invokes the function with 3 arguments: 1) the
   * next codepoint 2) a string of lookahead text 3) a boolean that
   * is true if the lookahead goes all the way to the EOF. (XXX
   * actually maybe this third is not necessary... the lookahead
   * could just include \uFFFF?)
   *
   * If the lookahead property of a state function is an integer, it
   * specifies the number of characters required. If it is a string,
   * then the scanner will scan for that string and return all
   * characters up to and including that sequence, or up to EOF.  If
   * the lookahead property is a regexp, then the scanner will match
   * the regexp at the current point and return the matching string.
   *
   * States that require lookahead are responsible for explicitly
   * consuming the characters they process. They do this by
   * incrementing nextchar by the number of processed characters.
