      • getUid

         abstract long getUid()

        A unique identifier of the text track cue.

         abstract double getStartTime()
        Returns:

        The playback position at which the cue becomes active, in seconds.

      • setStartTime

         abstract void setStartTime(double startTime)

        Set playback position at which the cue becomes active, in seconds.

      • getEndTime

         abstract double getEndTime()
        Returns:

        The playback position at which the cue becomes inactive, in seconds.

      • setEndTime

         abstract void setEndTime(double endTime)

        Set playback position at which the cue becomes inactive, in seconds.

      • getContent

        @Nullable() abstract JSONObject getContent()

        The content of the cue, it depends on the TextTrack's getType.

        • 'emsg': Content is a Uint8Array representing the binary message data from the 'emsg' box.
        • 'eventstream': Content is the value of the 'messageData' attribute which was specified in the manifest.
        • 'ttml': Content is an intermediate TTML document’s body element. This is a view of a TTML document where all nodes in the document are active during the cue’s startTime and endTime. As a result, all begin, dur and end properties have been removed. TTML Styles, Regions and Metadata are stored in cue.styles, cue.regions, cue.metadata respectively. Combining those properties with the given content should suffice to render a TTML cue.
        • 'webvtt': Content is the cue text in raw unparsed form.
        • Null when the type is unknown.
        Returns:

        The content of the cue, represented by a JSONObject. (Nullable)
