Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.\n *\n * 3. Use the player object to control the animation programmatically.\n *\n * For example:\n *\n * ```ts\n * // import the service from BrowserAnimationsModule\n * import {AnimationBuilder} from '@angular/animations';\n * // require the service as a dependency\n * class MyCmp {\n * constructor(private _builder: AnimationBuilder) {}\n *\n * makeAnimation(element: any) {\n * // first define a reusable animation\n * const myAnimation = this._builder.build([\n * style({ width: 0 }),\n * animate(1000, style({ width: '100px' }))\n * ]);\n *\n * // use the returned factory object to create a player\n * const player = myAnimation.create(element);\n *\n * player.play();\n * }\n * }\n * ```\n *\n * @publicApi\n */\nclass AnimationBuilder {\n}\n/**\n * A factory object returned from the\n * [AnimationBuilder.build](api/animations/AnimationBuilder#build)()\n * method.\n *\n * @publicApi\n */\nclass AnimationFactory {\n}\n\n/**\n * @license\n * Copyright Google LLC All Rights Reserved.\n *\n * Use of this source code is governed by an MIT-style license that can be\n * found in the LICENSE file at https://angular.io/license\n */\n/**\n * Specifies automatic styling.\n *\n * @publicApi\n */\nconst AUTO_STYLE = '*';\n/**\n * Creates a named animation trigger, containing a list of [`state()`](api/animations/state)\n * and `transition()` entries to be evaluated when the expression\n * bound to the trigger changes.\n *\n * @param name An identifying string.\n * @param definitions An animation definition object, containing an array of\n * [`state()`](api/animations/state) and `transition()` declarations.\n *\n * @return An object that encapsulates the trigger data.\n *\n * @usageNotes\n * Define an animation trigger in the `animations` section of `@Component` metadata.\n * In the template, reference the trigger by name and bind it to a trigger expression that\n * evaluates to a defined animation state, using the following format:\n *\n * `[@triggerName]=\"expression\"`\n *\n * Animation trigger bindings convert all values to strings, and then match the\n * previous and current values against any linked transitions.\n * Booleans can be specified as `1` or `true` and `0` or `false`.\n *\n * ### Usage Example\n *\n * The following example creates an animation trigger reference based on the provided\n * name value.\n * The provided animation value is expected to be an array consisting of state and\n * transition declarations.\n *\n * ```typescript\n * @Component({\n * selector: \"my-component\",\n * templateUrl: \"my-component-tpl.html\",\n * animations: [\n * trigger(\"myAnimationTrigger\", [\n * state(...),\n * state(...),\n * transition(...),\n * transition(...)\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"something\";\n * }\n * ```\n *\n * The template associated with this component makes use of the defined trigger\n * by binding to an element within its template code.\n *\n * ```html\n * \n * ...
\n * ```\n *\n * ### Using an inline function\n * The `transition` animation method also supports reading an inline function which can decide\n * if its associated animation should be run.\n *\n * ```typescript\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n string]: any}): boolean {\n * // notice that `element` and `params` are also available here\n * return toState == 'yes-please-animate';\n * }\n *\n * @Component({\n * selector: 'my-component',\n * templateUrl: 'my-component-tpl.html',\n * animations: [\n * trigger('myAnimationTrigger', [\n * transition(myInlineMatcherFn, [\n * // the animation sequence code\n * ]),\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"yes-please-animate\";\n * }\n * ```\n *\n * ### Disabling Animations\n * When true, the special animation control binding `@.disabled` binding prevents\n * all animations from rendering.\n * Place the `@.disabled` binding on an element to disable\n * animations on the element itself, as well as any inner animation triggers\n * within the element.\n *\n * The following example shows how to use this feature:\n *\n * ```typescript\n * @Component({\n * selector: 'my-component',\n * template: `\n * \n * \n *
\n * `,\n * animations: [\n * trigger(\"childAnimation\", [\n * // ...\n * ])\n * ]\n * })\n * class MyComponent {\n * isDisabled = true;\n * exp = '...';\n * }\n * ```\n *\n * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,\n * along with any inner animations.\n *\n * ### Disable animations application-wide\n * When an area of the template is set to have animations disabled,\n * **all** inner components have their animations disabled as well.\n * This means that you can disable all animations for an app\n * by placing a host binding set on `@.disabled` on the topmost Angular component.\n *\n * ```typescript\n * import {Component, HostBinding} from '@angular/core';\n *\n * @Component({\n * selector: 'app-component',\n * templateUrl: 'app.component.html',\n * })\n * class AppComponent {\n * @HostBinding('@.disabled')\n * public animationsDisabled = true;\n * }\n * ```\n *\n * ### Overriding disablement of inner animations\n * Despite inner animations being disabled, a parent animation can `query()`\n * for inner elements located in disabled areas of the template and still animate\n * them if needed. This is also the case for when a sub animation is\n * queried by a parent and then later animated using `animateChild()`.\n *\n * ### Detecting when an animation is disabled\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\n * an instance of an `AnimationEvent`.

\n *\n * ### Animating to a Final State\n *\n * If the final step in a transition is a call to `animate()` that uses a timing value\n * with no `style` data, that step is automatically considered the final animation arc,\n * for the element to reach the final state, in such case Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n *\n * ### Usage Examples\n *\n * - Transition animations applied based on\n * the trigger's expression value\n *\n * ```HTML\n * \n * ...\n *

Use the `limit` field of an options object to limit\n * the total number of items to be collected. For example:\n *\n * ```js\n * query('div', [\n * animate(...),\n * animate(...)\n * ], { limit: 1 })\n * ```\n *\n * By default, throws an error when zero items are found.

\n *\n * \n *\n * There is an exception to what previously mentioned, besides elements entering/leaving based on\n * their own logic, elements with an animation trigger can always be queried via `:leave` when\n * their parent is also leaving.\n *\n *

Overlap of animations\n * Given that a CSS property cannot be animated in more than one place at the same time, it's\n * important that this behavior is detected and validated. The way in which this occurs is that\n * each time a style property is examined, a string-map containing the property will be updated with\n * the start and end times for when the property is used within an animation step.\n *\n * If there are two or more parallel animations that are currently running (these are invoked by the\n * group()) on the same element then the validator will throw an error. Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3. Offset Validation\n * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n * Offsets within keyframes() are considered valid when:\n *\n * - No offsets are used at all\n * - Each style() entry contains an offset value\n * - Each offset is between 0 and 1\n * - Each offset is greater to or equal than the previous one\n *\n * Otherwise an error will be thrown.\n */\nfunction buildAnimationAst(driver, metadata, errors, warnings) {\n return new AnimationAstBuilderVisitor(driver).build(metadata, errors, warnings);\n}\nconst ROOT_SELECTOR = '';\nclass AnimationAstBuilderVisitor {\n constructor(_driver) {\n this._driver = _driver;\n }\n build(metadata, errors, warnings) {\n const context = new AnimationAstBuilderContext(errors);\n this._resetContextStyleTimingState(context);\n const ast = visitDslNode(this, normalizeAnimationEntry(metadata), context);\n if (typeof ngDevMode === 'undefined' || ngDevMode) {\n if (context.unsupportedCSSPropertiesFound.size) {\n pushUnrecognizedPropertiesWarning(warnings, [...context.unsupportedCSSPropertiesFound.keys()]);\n }\n }\n return ast;\n }\n _resetContextStyleTimingState(context) {\n context.currentQuerySelector = ROOT_SELECTOR;\n context.collectedStyles = new Map();\n context.collectedStyles.set(ROOT_SELECTOR, new Map());\n context.currentTime = 0;\n }\n visitTrigger(metadata, context) {\n let queryCount = context.queryCount = 0;\n let depCount = context.depCount = 0;\n const states = [];\n const transitions = [];\n if (metadata.name.charAt(0) == '@') {\n context.errors.push(invalidTrigger());\n }\n metadata.definitions.forEach(def => {\n this._resetContextStyleTimingState(context);\n if (def.type == 0 /* AnimationMetadataType.State */) {\n const stateDef = def;\n const name = stateDef.name;\n name.toString().split(/\\s*,\\s*/).forEach(n => {\n stateDef.name = n;\n states.push(this.visitState(stateDef, context));\n });\n stateDef.name = name;\n }\n else if (def.type == 1 /* AnimationMetadataType.Transition */) {\n const transition = this.visitTransition(def, context);\n queryCount += transition.queryCount;\n depCount += transition.depCount;\n transitions.push(transition);\n }\n else {\n context.errors.push(invalidDefinition());\n }\n });\n return {\n type: 7 /* AnimationMetadataType.Trigger */,\n name: metadata.name,\n states,\n transitions,\n queryCount,\n depCount,\n options: null\n };\n }\n visitState(metadata, context) {\n const styleAst = this.visitStyle(metadata.styles, context);\n const astParams = (metadata.options && metadata.options.params) || null;\n if (styleAst.containsDynamicStyles) {\n const missingSubs = new Set();\n const params = astParams || {};\n styleAst.styles.forEach(style => {\n if (style instanceof Map) {\n style.forEach(value => {\n extractStyleParams(value).forEach(sub => {\n if (!params.hasOwnProperty(sub)) {\n missingSubs.add(sub);\n }\n });\n });\n }\n });\n if (missingSubs.size) {\n const missingSubsArr = iteratorToArray(missingSubs.values());\n context.errors.push(invalidState(metadata.name, missingSubsArr));\n }\n }\n return {\n type: 0 /* AnimationMetadataType.State */,\n name: metadata.name,\n style: styleAst,\n options: astParams ?

This means\n * that when functional composition mix of these functions is evaluated (like in the example above)\n * then it will end up producing a tree of objects representing the animation itself.\n *\n * When this animation object tree is processed by the visitor code below it will visit each of the\n * verb statements within the visitor. And during each visit it will build the context of the\n * animation keyframes by interacting with the `TimelineBuilder`.\n *\n * [TimelineBuilder]\n * This class is responsible for tracking the styles and building a series of keyframe objects for a\n * timeline between a start and end time. The builder starts off with an initial timeline and each\n * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a\n * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n * they are complete.\n *\n * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergeSort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```\n * sequence([\n * style({ width: 0 }),\n * animate(1000, style({ width: 100 })),\n * animate(1000, style({ width: 200 })),\n * animate(1000, style({ width: 300 }))\n * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill map. The `copyStyles` method in util.ts\n * handles propagating that backfill map to the styles object.\n *\n * When a sub-timeline is created it will have its own backFill property. This is done so that\n * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n * keyframes\n *\n * [Validation]\n * The code in this file is not responsible for validation. That functionality happens with within\n * the `AnimationValidatorVisitor` code.\n */\nfunction buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles = new Map(), finalStyles = new Map(), options, subInstructions, errors = []) {\n return new AnimationTimelineBuilderVisitor().buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors);\n}\nclass AnimationTimelineBuilderVisitor {\n buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors = []) {\n subInstructions = subInstructions || new ElementInstructionMap();\n const context = new AnimationTimelineContext(driver, rootElement, subInstructions, enterClassName, leaveClassName, errors, []);\n context.options = options;\n const delay = options.delay ?
