The mechanism used, to\n * activate support for map-based bindings at runtime is possible via the\n * `activeStylingMapFeature` function (which is also present in this file).\n *\n * # The Algorithm\n * Whenever a map-based binding updates (which is when the identity of the\n * map-value changes) then the map is iterated over and a `StylingMapArray` array\n * is produced. The `StylingMapArray` instance is stored in the binding location\n * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`\n * instruction were called. Once the binding changes, then the internal `bitMask`\n * value is marked as dirty.\n *\n * Styling values are applied once CD exits the element (which happens when\n * the `select(n)` instruction is called or the template function exits). When\n * this occurs, all prop-based bindings are applied. If a map-based binding is\n * present then a special flushing function (called a sync function) is made\n * available and it will be called each time a styling property is flushed.\n *\n * The flushing algorithm is designed to apply styling for a property (which is\n * a CSS property or a className value) one by one. If map-based bindings\n * are present, then the flushing algorithm will keep calling the maps styling\n * sync function each time a property is visited. This way, the flushing\n * behavior of map-based bindings will always be at the same property level\n * as the current prop-based property being iterated over (because everything\n * is alphabetically sorted).\n *\n * Let's imagine we have the following HTML template code:\n *\n * ```html\n * <div [style]=\"{width:'100px', height:'200px', 'z-index':'10'}\"\n *      [style.width.px]=\"200\">...</div>\n * ```\n *\n * When CD occurs, both the `[style]` and `[style.width]` bindings\n * are evaluated. Then when the styles are flushed on screen, the\n * following operations happen:\n *\n * 1. `[style.width]` is attempted to be written to the element.\n *\n * 2.  Once that happens, the algorithm instructs the map-based\n *     entries (`[style]` in this case) to \"catch up\" and apply\n *     all values up to the `width` value. When this happens the\n *     `height` value is applied to the element (since it is\n *     alphabetically situated before the `width` property).\n *\n * 3. Since there are no more prop-based entries anymore, the\n *    loop exits and then, just before the flushing ends, it\n *    instructs all map-based bindings to \"finish up\" applying\n *    their values.\n *\n * 4. The only remaining value within the map-based entries is\n *    the `z-index` value (`width` got skipped because it was\n *    successfully applied via the prop-based `[style.width]`\n *    binding). Since all map-based entries are told to \"finish up\",\n *    the `z-index` value is iterated over and it is then applied\n *    to the element.\n *\n * The most important thing to take note of here is that prop-based\n * bindings are evaluated in order alongside map-based bindings.\n * This allows all styling across an element to be applied in O(n)\n * time (a similar algorithm is that of the array merge algorithm\n * in merge sort).\n */\nvar syncStylingMap = function (context, renderer, element, data, applyStylingFn, sanitizer, mode, targetProp, defaultValue) {\n    var targetPropValueWasApplied = false;\n    // once the map-based styling code is activate it is never deactivated.

hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected\n// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.\n// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.\n// When the recursion returns the initIndex will be 7 so E1 is skipped as it\n// has already been called in the recursively called checkAnUpdateView().\nfunction callLifecycleHooksChildrenFirst(view, lifecycles) {\n    if (!(view.def.nodeFlags & lifecycles)) {\n        return;\n    }\n    var nodes = view.def.nodes;\n    var initIndex = 0;\n    for (var i = 0; i < nodes.length; i++) {\n        var nodeDef = nodes[i];\n        var parent_1 = nodeDef.parent;\n        if (!parent_1 && nodeDef.flags & lifecycles) {\n            // matching root node (e.g. a pipe)\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        if ((nodeDef.childFlags & lifecycles) === 0) {\n            // no child matches one of the lifecycles\n            i += nodeDef.childCount;\n        }\n        while (parent_1 && (parent_1.flags & 1 /* TypeElement */) &&\n            i === parent_1.nodeIndex + parent_1.childCount) {\n            // last child of an element\n            if (parent_1.directChildFlags & lifecycles) {\n                initIndex = callElementProvidersLifecycles(view, parent_1, lifecycles, initIndex);\n            }\n            parent_1 = parent_1.parent;\n        }\n    }\n}\nfunction callElementProvidersLifecycles(view, elDef, lifecycles, initIndex) {\n    for (var i = elDef.nodeIndex + 1; i <= elDef.nodeIndex + elDef.childCount; i++) {\n        var nodeDef = view.def.nodes[i];\n        if (nodeDef.flags & lifecycles) {\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        // only visit direct children\n        i += nodeDef.childCount;\n    }\n    return initIndex;\n}\nfunction callProviderLifecycles(view, index, lifecycles, initIndex) {\n    var providerData = asProviderData(view, index);\n    if (!providerData) {\n        return;\n    }\n    var provider = providerData.instance;\n    if (!provider) {\n        return;\n    }\n    Services.setCurrentNode(view, index);\n    if (lifecycles & 1048576 /* AfterContentInit */ &&\n        shouldCallLifecycleInitHook(view, 512 /* InitState_CallingAfterContentInit */, initIndex)) {\n        provider.ngAfterContentInit();\n    }\n    if (lifecycles & 2097152 /* AfterContentChecked */) {\n        provider.ngAfterContentChecked();\n    }\n    if (lifecycles & 4194304 /* AfterViewInit */ &&\n        shouldCallLifecycleInitHook(view, 768 /* InitState_CallingAfterViewInit */, initIndex)) {\n        provider.ngAfterViewInit();\n    }\n    if (lifecycles & 8388608 /* AfterViewChecked */) {\n        provider.ngAfterViewChecked();\n    }\n    if (lifecycles & 131072 /* OnDestroy */) {\n        provider.ngOnDestroy();\n    }\n}\n\n/**\n * @license\n * Copyright Google Inc.

Instead, ngClass and ngStyle should have their input values be converted\n * into something that the core-level [style] and [class] bindings understand.\n *\n * This [StylingDiffer] class handles this conversion by creating a new input value each time\n * the inner representation of the binding value have changed.\n *\n * ## Why do we care about ngStyle/ngClass?\n * The styling algorithm code (documented inside of `render3/interfaces/styling.ts`) needs to\n * respect and understand the styling values emitted through ngStyle and ngClass (when they\n * are present and used in a template).\n *\n * Instead of having these directives manage styling on their own, they should be included\n * into the Angular styling algorithm that exists for [style] and [class] bindings.\n *\n * Here's why:\n *\n * - If ngStyle/ngClass is used in combination with [style]/[class] bindings then the\n *   styles and classes would fall out of sync and be applied and updated at\n *   inconsistent times\n * - Both ngClass/ngStyle do not respect [class.name] and [style.prop] bindings\n *   (they will write over them given the right combination of events)\n *\n *   ```\n *   <!-- if `w1` is updated then it will always override `w2`\n *        if `w2` is updated then it will always override `w1`\n *        if both are updated at the same time then `w1` wins -->\n *   <div [ngStyle]=\"{width:w1}\" [style.width]=\"w2\">...</div>\n *\n *   <!-- if `w1` is updated then it will always lose to `w2`\n *        if `w2` is updated then it will always override `w1`\n *        if both are updated at the same time then `w2` wins -->\n *   <div [style]=\"{width:w1}\" [style.width]=\"w2\">...</div>\n *   ```\n * - ngClass/ngStyle were written as a directives and made use of maps, closures and other\n *   expensive data structures which were evaluated each time CD runs\n */\nvar StylingDiffer = /** @class */ (function () {\n    function StylingDiffer(_name, _options) {\n        this._name = _name;\n        this._options = _options;\n        this.value = null;\n        this._lastSetValue = null;\n        this._lastSetValueType = 0 /* Null */;\n        this._lastSetValueIdentityChange = false;\n    }\n    /**\n     * Sets (updates) the styling value within the differ.\n     *\n     * Only when `hasValueChanged` is called then this new value will be evaluted\n     * and checked against the previous value.\n     *\n     * @param value the new styling value provided from the ngClass/ngStyle binding\n     */\n    StylingDiffer.prototype.setValue = function (value) {\n        if (Array.isArray(value)) {\n            this._lastSetValueType = 4 /* Array */;\n        }\n        else if (value instanceof Set) {\n            this._lastSetValueType = 8 /* Set */;\n        }\n        else if (value && typeof value === 'string') {\n            if (!(this._options & 4 /* AllowStringValue */)) {\n                throw new Error(this._name + ' string values are not allowed');\n            }\n            this._lastSetValueType = 1 /* String */;\n        }\n        else {\n            this._lastSetValueType = value ? 2 /* Map */ : 0 /* Null */;\n        }\n        this._lastSetValueIdentityChange = true;\n        this._lastSetValue = value || null;\n    };\n    /**\n     * Determines whether or not the value has changed.\n     *\n     * This function can be called right after `setValue()` is called, but it can also be\n     * called incase the existing value (if it's a collection) changes internally.

Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ### Change propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls that are present, such as `<input>` elements that accept user input.

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

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }}               // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'\n * {{ dateObj | date:'mm:ss' }}       // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * @Component({\n *  selector: 'date-pipe',\n *  template: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n * @publicApi\n */\n// clang-format on\nvar DatePipe = /** @class */ (function () {\n    function DatePipe(locale) {\n        this.locale = locale;\n    }\n    DatePipe_1 = DatePipe;\n
