Class AbstractListenerContainer

  • All Implemented Interfaces:
    ListenerContainerIF
    Direct Known Subclasses:
    CompositeConfigurationListener, CompositeConnectionListener, CompositeProxoolListener, CompositeStateListener, CompositeStatisticsListener

    public abstract class AbstractListenerContainer
    extends java.lang.Object
    implements ListenerContainerIF
    Implementation of ListenerContainerIF that uses a reads/write lock to handle concurrency in a safe and fast way.

    The registered listeners are offered to subclasses through the protected getListeners() method. This method returns a reference to an array containing the registered listeners. A new array holding the listeners is created everytime a modification on the registration list is required (add/remove listener). Therefore, subclasses can safely iterate over the received array. Your code sould look like this:

         Object[] listeners = getListeners();
         for(int i=0; i
