Interface NodeListener

EventListener, PropertyChangeListener
All Known Implementing Classes:
FilterNode.NodeAdapter, NodeAdapter

public interface NodeListener
extends PropertyChangeListener

Listener to special changes in Nodes. Is a property change listener so that all changes in properties in the node can be fired in the usual way.

Methods childrenAdded, childrenRemoved and childrenReordered are called with Children.MUTEX.writeAccess which guarantees that no other thread can change the hierarchy during that time, but also requires proper implementation of all NodeListeners which should avoid calls to other threads which might require access to Children.MUTEX due to changes nodes hierarchy or do any other kind of starvation.
