AWTEventMulticaster
- class java.awt..AWTEventMulticaster public class AWTEventMulticaster extends Object implements ComponentListener , ContainerListener , FocusListener , KeyListener , MouseListener , MouseMotionListener , WindowListener , ActionListener , ItemListener , AdjustmentListener , TextListener , InputMethodListener Tree:java.lang.Object - java.awt.AWTEventMulticaster 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: AWTEventMulticaster(EventListener, EventListener) - Constructor for class java.awt.AWTEventMulticaster protected AWTEventMulticaster (EventListener a, EventListener b) Creates an event multicaster instance which chains listener-a with listener-b. Input parameters a and b should not be null, though implementations may vary in choosing whether or not to throw NullPointerException in that case.Parameters: a - listener-a - listener-bb - listener-b | ||||
