Type declaration

  • ReadonlycurrentState: MediaPlayback.PlaybackState

    Indicates the current playback state of media.

    During fast-forward, rewind, and other seek operations; this attribute shall be set to PLAYING.

    Static Readonlysupervisor

    supervisor: RootSupervisor

    Staticsupports

    supports: ((other: Type) => boolean)

    Type declaration

      • (other): boolean

      • Does this behavior support functionality of a specific implementation?

        Parameters

        Returns boolean

    Methods

    [asyncDispose]

    asAdmin

    • asAdmin(fn): void

    • Execute logic with elevated privileges.

      The provided function executes with privileges escalated to offline mode. This is not commonly necessary.

      Elevated logic effectively ignores ACLs so should be used with care.

      Note that interactions with the behavior will remain elevated until the synchronous completion of this call. You should only elevate privileges for synchronous logic.

      Parameters

      • fn: (() => void)

        the elevated logic

          • (): void

          • Returns void

      Returns void

    assertAttributeEnabled

    • assertAttributeEnabled<This, K>(this, attributeName): void

    • Type Parameters

      • This extends Behavior
      • K extends string | number | symbol

      Parameters

      • this: This
      • attributeName: K

      Returns void

    Protectedcallback

    • callback<A, R>(reactor, options?): ((...args: A) => undefined | R)

    • Create a generic callback function that has the same properties as a Reactor.

      Like a reactor, the callback's "this" will be bound to an active Behavior instance. Because of this: The reactor MUST be a real JS function - arrow functions will not work!

      Type Parameters

      • A extends any[]
      • R

      Parameters

      Returns ((...args: A) => undefined | R)

        • (...args): undefined | R

        • Parameters

          • Rest...args: A

          Returns undefined | R

    initialize

    • initialize(_options?): MaybePromise

    • Behaviors are ephemeral and should not perform initialization in their constructor. They can override this method instead.

      This method may be synchronous or asyncronous. If asynchronous, the behavior will not be available for external use until initialization completes.

      Parameters

      • Optional_options: {}

        Returns MaybePromise

      next

      pause

      play

      previous

      ProtectedreactTo

      • reactTo<O>(observable, reactor, options?): void

      • Install a Reactor.

        Important: The reactor MUST be a real JS function - arrow functions will not work!

        Type Parameters

        Parameters

        Returns void

      requireAttributeEnabled

      • requireAttributeEnabled<This, K>(this, attributeName): Exclude<This["state"][K], undefined>

      • Type Parameters

        • This extends Behavior
        • K extends string | number | symbol

        Parameters

        • this: This
        • attributeName: K

        Returns Exclude<This["state"][K], undefined>

      skipBackward

      skipForward

      startOver

      stop

      toString

      • toString(): string

      • Description used in diagnostic messages.

        Returns string

      Staticalter

      Staticenable

      Staticfor

      Staticset

      • set<This>(this, defaults): This

      • Type Parameters

        Parameters

        Returns This
