Use the `build()` method to create a programmatic animation using the\n * `animate()` function. The method returns an `AnimationFactory` instance.\n *\n * 2. 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 `AnimationBuilder`.`build()` 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()`\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 `state()`\n * 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 * 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`. If animations are disabled,\n * the `.disabled` flag on the event is true.\n *\n * @publicApi\n */\nfunction trigger(name, definitions) {\n return { type: 7 /* Trigger */, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\n * @param timings Sets `AnimateTimings` for the parent animation.\n * A string in the format \"duration [delay] [easing]\".\n * - Duration and delay are expressed as a number and optional time unit,\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\n * The default unit is milliseconds.\n * - The easing value controls how the animation accelerates and decelerates\n * during its runtime.

Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n * The following example defines a transition that starts by hiding the element,\n * then makes sure that it animates properly to whatever state is currently active for trigger:\n *\n * ```typescript\n * transition(\"void => *\", [\n * style({ opacity: 0 }),\n * animate(500)\n * ])\n * ```\n * ### Boolean value matching\n * If a trigger binding value is a Boolean, it can be matched using a transition expression\n * that compares true and false or 1 and 0. For example:\n *\n * ```\n * // in the template\n *
...
\n * // in the component metadata\n * trigger('openClose', [\n * state('true', style({ height: '*' })),\n * state('false', style({ height: '0px' })),\n * transition('false <=> true', animate(500))\n * ])\n * ```\n *\n * @publicApi\n **/\nfunction transition(stateChangeExpr, steps, options = null) {\n return { type: 1 /* Transition */, expr: stateChangeExpr, animation: steps, options };\n}\n/**\n * Produces a reusable animation that can be invoked in another animation or sequence,\n * by calling the `useAnimation()` function.\n *\n * @param steps One or more animation objects, as returned by the `animate()`\n * or `sequence()` function, that form a transformation from one state to another.\n * A sequence is used by default when you pass an array.\n * @param options An options object that can contain a delay value for the start of the\n * animation, and additional developer-defined parameters.\n * Provided values for additional parameters are used as defaults,\n * and override values can be passed to the caller on invocation.\n * @returns An object that encapsulates the animation data.\n *\n * @usageNotes\n * The following example defines a reusable animation, providing some default parameter\n * values.\n *\n * ```typescript\n * var fadeAnimation = animation([\n * style({ opacity: '{{ start }}' }),\n * animate('{{ time }}',\n * style({ opacity: '{{ end }}'}))\n * ],\n * { params: { time: '1000ms', start: 0, end: 1 }});\n * ```\n *\n * The following invokes the defined animation with a call to `useAnimation()`,\n * passing in override parameter values.\n *\n * ```js\n * useAnimation(fadeAnimation, {\n * params: {\n * time: '2s',\n * start: 1,\n * end: 0\n * }\n * })\n * ```\n *\n * If any of the passed-in parameter values are missing from this call,\n * the default values are used.

Specifically, this\n * regular expression matches if (comment from here on and regex copied from\n * Soy's EscapingConventions):\n * (1) Either an allowed protocol (http, https, mailto or ftp).\n * (2) or no protocol. A protocol must be followed by a colon. The below\n * allows that by allowing colons only after one of the characters [/?#].\n * A colon after a hash (#) must be in the fragment.\n * Otherwise, a colon after a (?) must be in a query.\n * Otherwise, a colon after a single solidus (/) must be in a path.\n * Otherwise, a colon after a double solidus (//) must be in the authority\n * (before port).\n *\n * The pattern disallows &, used in HTML entity declarations before\n * one of the characters in [/?#]. This disallows HTML entities used in the\n * protocol name, which should never happen, e.g. \"http\" for \"http\".\n * It also disallows HTML entities in the first path part of a relative path,\n * e.g. \"foo<bar/baz\". Our existing escaping functions should not produce\n * that. More importantly, it disallows masking of a colon,\n * e.g. \"javascript:...\".\n *\n * This regular expression was taken from the Closure sanitization library.\n */\nconst SAFE_URL_PATTERN = /^(?:(?:https?|mailto|ftp|tel|file|sms):|[^&:/?#]*(?:[/?#]|$))/gi;\n/* A pattern that matches safe srcset values */\nconst SAFE_SRCSET_PATTERN = /^(?:(?:https?|file):|[^&:/?#]*(?:[/?#]|$))/gi;\n/** A pattern that matches safe data URLs.
