Unsafe: A class which implements efficient and thread-safe multi-cast event dispatching for the AWT events defined in the java.awt.event package. This class will manage an immutable structure consisting of a chain of event listeners and will dispatch events to those listeners. Because the structure is immutable, it is safe to use this API to add/remove listeners during the process of an event dispatch operation. An example of how this class could be used to implement a new component which fires "action" events:

 public myComponent extends Component {
     ActionListener actionListener = null;

     public synchronized void addActionListener(ActionListener l) {
	   actionListener = AWTEventMulticaster.add(actionListener, l);
     }
     public synchronized void removeActionListener(ActionListener l) {
  	   actionListener = AWTEventMulticaster.remove(actionListener, l);
     }
     public void processEvent(AWTEvent e) {
         // when event occurs which causes "action" semantic
         if (actionListener != null) {
             actionListener.actionPerformed(new ActionEvent());
         }         
 }
