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: <pre><code> 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()); } } </code></pre><P><DL><DT><B>Since: </B><DD>1.1</DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY
