public class EventDispatcherImpl extends Object implements EventDispatcher
An implementation of the EventDispatcher interface. Since Java
doesn't support multiple inheritance, you could follow the Log.java
style: this class should be instantiated and kept as a variable by
each object it is used by, ala:
private final EventDispatcher _event = new EventDispatcher();
Deprecated - Used only by I2PTunnel
