Field Detail

listenerList	back to summary
private List<NotificationEmitterSupport.ListenerInfo> listenerList Current list of listeners, a List of ListenerInfo. The object referenced by this field is never modified. Instead, the field is set to a new object when a listener is added or removed, within a synchronized(this). In this way, there is no need to synchronize when traversing the list to send a notification to the listeners in it. That avoids potential deadlocks if the listeners end up depending on other threads that are themselves accessing this NotificationBroadcasterSupport.
