Constructor Detail

SyncListener

public SyncListener(EventList<E> source,
                    java.util.List<E> target)

Create a SyncListener that listens for changes on the specified source EventList and copies its data to the specified target List.

Method Detail

listChanged

public void listChanged(ListEvent<E> listChanges)

When the underlying list changes, this notification allows the object to repaint itself or update itself as necessary.

It is mandatory that the calling thread has obtained the write lock on the source list. This is because the calling thread will have written to the source list to cause this event. This condition guarantees that no writes can occur while the listener is handling this event. It is an error to write to the source list while processing an event.

Specified by:

listChanged in interface ListEventListener<E>

Parameters:

listChanges - a ListEvent describing the changes to the list

dispose

public void dispose()

Stops the synchronization between the two lists by removing the ListEventListener from the source list. After disposing this listener is non-functional and should be discarded.
