 * Base type of all events.
 * 
 * 

Events are passed between elements in parallel to the data stream. Some events * are serialized with buffers, others are not. Some events only travel downstream, * others only upstream. Some events can travel both upstream and downstream. * *

The events are used to signal special conditions in the datastream such as * EOS (end of stream) or the start of a new stream-segment. * *

Events are also used to flush the pipeline of any pending data. * * @see Pad#pushEvent * @see Pad#sendEvent * @see Element#sendEvent */ @HasSubtype public class Event extends MiniObject { private static interface API extends com.sun.jna.Library { Structure gst_event_get_structure(Event event); } private static final API gst = GstNative.load(API.class); /** * This constructor is for internal use only. * @param init initialization data. */ public Event(Initializer init) { super(init); } /** * Gets the structure containing the data in this event. * * @return a structure. */ public Structure getStructure() { return ReferenceManager.addKeepAliveReference(gst.gst_event_get_structure(this), this); } }
