Class EventListenerList

java.lang.Object
  |
  +--org.lirc.EventListenerList

All Implemented Interfaces:

java.io.Serializable

public class EventListenerList

extends java.lang.Object

implements java.io.Serializable

Simliar to javax.swing.EventListener, but easier to use. Usage:

 EventListenerList listenerList = new EventListenerList();
 FooEvent fooEvent = null;

 public void addFooListener(FooListener l) {
     listenerList.add(FooListener.class, l);
 }

 public void removeFooListener(FooListener l) {
     listenerList.remove(FooListener.class, l);
 }

 protected void fireFooXXX() {
     FooEvent e = null;
     EventListener[] ls = listenerList.getListeners(FooListener.class);
     for (int j = ls.length-1; j >= 0; j--) {
        FooListener l = (FooListener)ls[j];
        if (e == null) e = new FooEvent();
        l.fireFooXXX(e);
     }
 }
