*\r\n * @param timings Sets `AnimateTimings` for the parent animation.\r\n * A string in the format \"duration [delay] [easing]\".\r\n *  - Duration and delay are expressed as a number and optional time unit,\r\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\r\n * The default unit is milliseconds.\r\n *  - The easing value controls how the animation accelerates and decelerates\r\n * during its runtime. Value is one of  `ease`, `ease-in`, `ease-out`,\r\n * `ease-in-out`, or a `cubic-bezier()` function call.\r\n * If not supplied, no easing is applied.\r\n *\r\n * For example, the string \"1s 100ms ease-out\" specifies a duration of\r\n * 1000 milliseconds, and delay of 100 ms, and the \"ease-out\" easing style,\r\n * which decelerates near the end of the duration.\r\n * @param styles Sets AnimationStyles for the parent animation.\r\n * A function call to either `style()` or `keyframes()`\r\n * that returns a collection of CSS style entries to be applied to the parent animation.\r\n * When null, uses the styles from the destination state.\r\n * This is useful when describing an animation step that will complete an animation;\r\n * see \"Animating to the final state\" in `transitions()`.\r\n * @returns An object that encapsulates the animation step.\r\n *\r\n * @usageNotes\r\n * Call within an animation `sequence()`, `{@link animations/group group()}`, or\r\n * `transition()` call to specify an animation step\r\n * that applies given style data to the parent animation for a given amount of time.\r\n *\r\n * ### Syntax Examples\r\n * **Timing examples**\r\n *\r\n * The following examples show various `timings` specifications.\r\n * - `animate(500)` : Duration is 500 milliseconds.\r\n * - `animate(\"1s\")` : Duration is 1000 milliseconds.\r\n * - `animate(\"100ms 0.5s\")` : Duration is 100 milliseconds, delay is 500 milliseconds.\r\n * - `animate(\"5s ease-in\")` : Duration is 5000 milliseconds, easing in.\r\n * - `animate(\"5s 10ms cubic-bezier(.17,.67,.88,.1)\")` : Duration is 5000 milliseconds, delay is 10\r\n * milliseconds, easing according to a bezier curve.\r\n *\r\n * **Style examples**\r\n *\r\n * The following example calls `style()` to set a single CSS style.\r\n * ```typescript\r\n * animate(500, style({ background: \"red\" }))\r\n * ```\r\n * The following example calls `keyframes()` to set a CSS style\r\n * to different values for successive keyframes.\r\n * ```typescript\r\n * animate(500, keyframes(\r\n *  [\r\n *   style({ background: \"blue\" }),\r\n *   style({ background: \"red\" })\r\n *  ])\r\n * ```\r\n *\r\n * @publicApi\r\n */\r\nexport declare function animate(timings: string | number, styles?: AnimationStyleMetadata | AnimationKeyframesSequenceMetadata | null): AnimationAnimateMetadata;\r\n\r\n/**\r\n * Executes a queried inner animation element within an animation sequence.\r\n *\r\n * @param options An options object that can contain a delay value for the start of the\r\n * animation, and additional override values for developer-defined parameters.\r\n * @return An object that encapsulates the child animation data.\r\n *\r\n * @usageNotes\r\n * Each time an animation is triggered in Angular, the parent animation\r\n * has priority and any child animations are blocked.

Angular automatically adds or removes\r\n * CSS styles to ensure that the element is in the correct final state.\r\n *\r\n * The following example defines a transition that starts by hiding the element,\r\n * then makes sure that it animates properly to whatever state is currently active for trigger:\r\n *\r\n * ```typescript\r\n * transition(\"void => *\", [\r\n *   style({ opacity: 0 }),\r\n *   animate(500)\r\n *  ])\r\n * ```\r\n * ### Boolean value matching\r\n * If a trigger binding value is a Boolean, it can be matched using a transition expression\r\n * that compares true and false or 1 and 0. For example:\r\n *\r\n * ```\r\n * // in the template\r\n * <div [@openClose]=\"open ? true : false\">...</div>\r\n * // in the component metadata\r\n * trigger('openClose', [\r\n *   state('true', style({ height: '*' })),\r\n *   state('false', style({ height: '0px' })),\r\n *   transition('false <=> true', animate(500))\r\n * ])\r\n * ```\r\n *\r\n * @publicApi\r\n **/\r\nexport declare

 transition(...),\r\n *       transition(...)\r\n *     ])\r\n *   ]\r\n * })\r\n * class MyComponent {\r\n *   myStatusExp = \"something\";\r\n * }\r\n * ```\r\n *\r\n * The template associated with this component makes use of the defined trigger\r\n * by binding to an element within its template code.\r\n *\r\n * ```html\r\n * <!-- somewhere inside of my-component-tpl.html -->\r\n * <div [@myAnimationTrigger]=\"myStatusExp\">...</div>\r\n * ```\r\n *\r\n * ### Using an inline function\r\n * The `transition` animation method also supports reading an inline function which can decide\r\n * if its associated animation should be run.\r\n *\r\n * ```typescript\r\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\r\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\r\n string]: any}): boolean {\r\n *   // notice that `element` and `params` are also available here\r\n *   return toState == 'yes-please-animate';\r\n * }\r\n *\r\n * @Component({\r\n *   selector: 'my-component',\r\n *   templateUrl: 'my-component-tpl.html',\r\n *   animations: [\r\n *     trigger('myAnimationTrigger', [\r\n *       transition(myInlineMatcherFn, [\r\n *         // the animation sequence code\r\n *       ]),\r\n *     ])\r\n *   ]\r\n * })\r\n * class MyComponent {\r\n *   myStatusExp = \"yes-please-animate\";\r\n * }\r\n * ```\r\n *\r\n * ### Disabling Animations\r\n * When true, the special animation control binding `@.disabled` binding prevents\r\n * all animations from rendering.\r\n * Place the  `@.disabled` binding on an element to disable\r\n * animations on the element itself, as well as any inner animation triggers\r\n * within the element.\r\n *\r\n * The following example shows how to use this feature:\r\n *\r\n * ```typescript\r\n * @Component({\r\n *   selector: 'my-component',\r\n *   template: `\r\n *     <div [@.disabled]=\"isDisabled\">\r\n *       <div [@childAnimation]=\"exp\"></div>\r\n *     </div>\r\n *   `,\r\n *   animations: [\r\n *     trigger(\"childAnimation\", [\r\n *       // ...\r\n *     ])\r\n *   ]\r\n * })\r\n * class MyComponent {\r\n *   isDisabled = true;\r\n *   exp = '...';\r\n * }\r\n * ```\r\n *\r\n * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,\r\n * along with any inner animations.\r\n *\r\n * ### Disable animations application-wide\r\n * When an area of the template is set to have animations disabled,\r\n * **all** inner components have their animations disabled as well.\r\n * This means that you can disable all animations for an app\r\n * by placing a host binding set on `@.disabled` on the topmost Angular component.\r\n *\r\n * ```typescript\r\n * import {Component, HostBinding} from '@angular/core';\r\n *\r\n * @Component({\r\n *   selector: 'app-component',\r\n *   templateUrl: 'app.component.html',\r\n * })\r\n * class AppComponent {\r\n *   @HostBinding('@.disabled')\r\n *   public animationsDisabled = true;\r\n * }\r\n * ```\r\n *\r\n * ### Overriding disablement of inner animations\r\n * Despite inner animations being disabled, a parent animation can `query()`\r\n * for inner elements located in disabled areas of the template and still animate\r\n * them if needed. This is also the case for when a sub animation is\r\n * queried by a parent and then later animated using `animateChild()`.\r\n *\r\n * ### Detecting when an animation is disabled\r\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\r\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\r\n * an instance of an `AnimationEvent`. If animations are disabled,\r\n * the `.disabled` flag on the event is true.\r\n *\r\n * @publicApi\r\n */\r\nexport declare function trigger(name: string, definitions: AnimationMetadata[]): AnimationTriggerMetadata;\r\n\r\n/**\r\n * Starts a reusable animation that is created using the `animation()` function.\r\n *\r\n * @param animation The reusable animation to start.\r\n * @param options An options object that can contain a delay value for the start of\r\n * the animation, and additional override values for developer-defined parameters.\r\n * @return An object that contains the animation parameters.\r\n *\r\n * @publicApi\r\n */\r\nexport declare function useAnimation(animation: AnimationReferenceMetadata, options?: AnimationOptions | null): AnimationAnimateRefMetadata;\r\n\r\n/**\r\n * A programmatic controller for a group of reusable animations.\r\n * Used internally to control animations.\r\n *\r\n * @see `AnimationPlayer`\r\n * @see `{@link animations/group group()}`\r\n *\r\n */\r\nexport declare class ɵAnimationGroupPlayer implements AnimationPlayer {\r\n    private _onDoneFns;\r\n    private _onStartFns;\r\n    private _finished;\r\n    private _started;\r\n    private _destroyed;\r\n    private _onDestroyFns;\r\n    parentPlayer: AnimationPlayer | null;\r\n    totalTime: number;\r\n    readonly players: AnimationPlayer[];\r\n    constructor(_players: AnimationPlayer[]);\r\n    private _onFinish;\r\n    init(): void;\r\n    onStart(fn: () => void): void;\r\n    private _onStart;\r\n    onDone(fn: () => void): void;\r\n    onDestroy(fn: () => void): void;\r\n    hasStarted(): boolean;\r\n    play(): void;\r\n    pause(): void;\r\n    restart(): void;\r\n    finish(): void;\r\n    destroy(): void;\r\n    private _onDestroy;\r\n    reset(): void;\r\n    setPosition(p: number): void;\r\n    getPosition(): number;\r\n    beforeDestroy(): void;\r\n}\r\n\r\nexport declare const ɵPRE_STYLE = \"!\";\r\n\r\n\r\n/**\r\n * Represents a set of CSS styles for use in an animation style.\r\n */\r\nexport declare interface ɵStyleData {\r\n    [key: string]: string | number;\r\n}\r\n\r\nexport { }\r\n"]}
