英语翻译
The event sources don’t need to implement an interface or extend some class to be a source.However,they must keep a list of event listeners who have registered for events from this source.The listeners are registered with the source by calling addXXX Listener(XXX Listener) .To remove them from the list,call removeXXX Listener(XXX Listener).XXX is replaced by the name of the event type.Generally speaking,event sources can be unicast (only one listener allowed) or multicast (multiple listeners allowed).Within AWT and Swing,all event sources are multicast.To make things easier,a specialized Multicaster exists,java.awt.AWTEventMulticaster.The AWTEventMulticaster provides an efficient and thread-safe multicast event dispatching for the AWT events defined in the java.awt.event package [JLS].
