AWTEventMulticaster (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences.

java.awt
class AWTEventMulticaster

java.lang.Object
  java.awt.AWTEventMulticaster

All Implemented Interfaces:: ActionListener, AdjustmentListener, ComponentListener, ContainerListener, FocusListener, HierarchyBoundsListener, HierarchyListener, InputMethodListener, ItemListener, KeyListener, MouseListener, MouseMotionListener, MouseWheelListener, TextListener, WindowFocusListener, WindowListener, WindowStateListener

public class AWTEventMulticaster
extends Object
implements ComponentListener, ContainerListener, FocusListener, KeyListener, MouseListener, MouseMotionListener, WindowListener, WindowFocusListener, WindowStateListener, ActionListener, ItemListener, AdjustmentListener, TextListener, InputMethodListener, HierarchyListener, HierarchyBoundsListener, MouseWheelListener

{@code AWTEventMulticaster} implements efficient and thread-safe multi-cast event dispatching for the AWT events defined in the {@code java.awt.event} package.

The following example illustrates how to use this class:


 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
         ActionListener listener = actionListener;
         if (listener != null) {
             listener.actionPerformed(new ActionEvent());
         }
     }
 }

The important point to note is the first argument to the {@code add} and {@code remove} methods is the field maintaining the listeners. In addition you must assign the result of the {@code add} and {@code remove} methods to the field maintaining the listeners.

{@code AWTEventMulticaster} is implemented as a pair of {@code EventListeners} that are set at construction time. {@code AWTEventMulticaster} is immutable. The {@code add} and {@code remove} methods do not alter {@code AWTEventMulticaster} in anyway. If necessary, a new {@code AWTEventMulticaster} is created. In this way it is safe to add and remove listeners during the process of an event dispatching. However, event listeners added during the process of an event dispatch operation are not notified of the event currently being dispatched.

All of the {@code add} methods allow {@code null} arguments. If the first argument is {@code null}, the second argument is returned. If the first argument is not {@code null} and the second argument is {@code null}, the first argument is returned. If both arguments are {@code non-null}, a new {@code AWTEventMulticaster} is created using the two arguments and returned.

For the {@code remove} methods that take two arguments, the following is returned:

{@code null}, if the first argument is {@code null}, or the arguments are equal, by way of {@code ==}.
the first argument, if the first argument is not an instance of {@code AWTEventMulticaster}.
result of invoking {@code remove(EventListener)} on the first argument, supplying the second argument to the {@code remove(EventListener)} method.

Swing makes use of {@link javax.swing.event.EventListenerList EventListenerList} for similar logic. Refer to it for details.
