Classes that extend this adapter can easily replace only the message handlers they are interested in. For example, the following code extends a ControllerAdapter with a JDK 1.1 anonymous inner-class to make a self-contained player that resets itself back to the beginning and deallocates itself when the player reaches the end of the media: <code> player.addControllerListener(new ControllerAdapter() { public void endOfMedia(EndOfMediaEvent e) { Controller controller = e.getSource(); controller.stop(); controller.setMediaTime(0); controller.deallocate(); } }); </code><P><DL><DT><B>See Also: </B><DD><A
