Class Timeline.Period

  • All Implemented Interfaces:
    Bundleable
    Enclosing class:
    Timeline
    public static final class Timeline.Period
extends Object
implements Bundleable
    Holds information about a period in a Timeline. A period defines a single logical piece of media, for example a media file. It may also define groups of ads inserted into the media, along with information about whether those ads have been loaded and played.

    The figure below shows some of the information defined by a period, as well as how this information relates to a corresponding Timeline.Window in the timeline.
