◆ CaptionTimingAdapter()

alexaClientSDK::captions::CaptionTimingAdapter::CaptionTimingAdapter ( std::shared_ptr< CaptionPresenterInterface presenter,
std::shared_ptr< DelayInterface delayInterface 


presenterThe CaptionPresenterInterface which should receive caption frames that are ready to display.
delayInterfaceThe DelayInterface to use while waiting to display the next caption frame.

◆ pause()

virtual void alexaClientSDK::captions::CaptionTimingAdapter::pause ( )

Pauses the playback of captions, keeping track of the last caption frame shown.

Implements alexaClientSDK::captions::CaptionTimingAdapterInterface.

◆ queueForDisplay()

virtual void alexaClientSDK::captions::CaptionTimingAdapter::queueForDisplay ( const CaptionFrame captionFrame,
bool  autostart 

Enqueues a CaptionFrame object for display. This method must begin the serial presentation of the enqueued caption frames if such presentation is not already taking place and autostart is true. The order of the caption frames must be maintained as first-in-first-out.

captionFrameThe CaptionFrame object to be enqueued for display.
autostartDetermines if presentation should begin immediately if it has not already; defaults to true.

Implements alexaClientSDK::captions::CaptionTimingAdapterInterface.

◆ reset()

virtual void alexaClientSDK::captions::CaptionTimingAdapter::reset ( )

Resets the state of this adapter, in preparation for new captions content.

Implements alexaClientSDK::captions::CaptionTimingAdapterInterface.

◆ start()

virtual void alexaClientSDK::captions::CaptionTimingAdapter::start ( )

Resumes the playback of captions content, starting from the caption frame following the last one shown.

Implements alexaClientSDK::captions::CaptionTimingAdapterInterface.

◆ stop()

virtual void alexaClientSDK::captions::CaptionTimingAdapter::stop ( )

Stops the playback of captions, forgetting which caption frame was last shown.

Implements alexaClientSDK::captions::CaptionTimingAdapterInterface.
