    • addListener

      public void addListener(IConcurrentModelListener listener)
      Description copied from interface: IConcurrentModel
      Adds a listener to this model. The listener should be given the model's current contents (either through setContents or a sequence of adds) at the receiver's earliest convenience. The receiver will notify the listener about any changes in state until the listener is removed.

      Has no effect if an identical listener is already registered.

      Specified by:
      addListener in interface IConcurrentModel
      Parameters:
      listener - listener to add
    • fireAdd

      protected final void fireAdd(Object[] added)
      Fires an add notification to all listeners

    • fireRemove

      protected final void fireRemove(Object[] removed)
      Fires a remove notification to all listeners
      Parameters:

    • removeListener

      public void removeListener(IConcurrentModelListener listener)
      Description copied from interface: IConcurrentModel
      Removes a listener from this model. The receiver will stop sending notifications to the given listener as soon as possible (although some additional notifications may still if arrive if the receiver was in the process of sending notifications in another thread). Any pending updates for this listener will be cancelled.

      Has no effect if the given listener is not known to this model.

      Specified by:
      removeListener in interface IConcurrentModel
      Parameters:
      listener - listener to remove
