Class MediaTimer
java.lang.Object
org.ocap.media.MediaTimer
public class MediaTimer
- extends java.lang.Object
This is a timer class that counts time based on a media time of a specified Player. A media time is specified by the JMF specification. An application can specify a range between a first time and a last time. When a current media time exceeds this range, this timer fires and calls a MediaTimerListener.notify() method. I.e., when a current media time passes the last time, this timer fires and calls the notify() method with MEDIA_WENTOFF_LAST event. On the other hand, when a current media time passes the first time in a reverse playback or a skip playback, this timer fires and calls the notify() method with MEDIA_WENTOFF_FIRST event.
