Access the behavior's state.

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.

    See

    MatterSpecification.v13.Cluster § 6.10.6.1

Methods

[asyncDispose]

  • [asyncDispose](): MaybePromise

  • Release resources. This is the public API for releasing application resources held by behaviors in internal state.

    Returns MaybePromise

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

    • next(): MaybePromise<MediaPlayback.PlaybackResponse>

    • Upon receipt, this shall cause the handler to be invoked for "Next". User experience is context- specific. This will often Go forward to the next media playback item.

      Returns MaybePromise<MediaPlayback.PlaybackResponse>

      See

      MatterSpecification.v13.Cluster § 6.10.7.6

    pause

    play

    • play(): MaybePromise<MediaPlayback.PlaybackResponse>

    • Upon receipt, this shall play media. If content is currently in a FastForward or Rewind state. Play shall return media to normal playback speed.

      Returns MaybePromise<MediaPlayback.PlaybackResponse>

      See

      MatterSpecification.v13.Cluster § 6.10.7.1

    previous

    • previous(): MaybePromise<MediaPlayback.PlaybackResponse>

    • Upon receipt, this shall cause the handler to be invoked for "Previous". User experience is context-specific. This will often Go back to the previous media playback item.

      Returns MaybePromise<MediaPlayback.PlaybackResponse>

      See

      MatterSpecification.v13.Cluster § 6.10.7.5

    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

    • stop(): MaybePromise<MediaPlayback.PlaybackResponse>

    • Upon receipt, this shall stop playback of the media. User-visible outcome is context-specific. This may navigate the user back to the location from where the media was originally launched.

      Returns MaybePromise<MediaPlayback.PlaybackResponse>

      See

      MatterSpecification.v13.Cluster § 6.10.7.3

    toString

    • toString(): string

    • Description used in diagnostic messages.

      Returns string
