Interface NodeListener

All Superinterfaces:

EventListener, PropertyChangeListener

All Known Implementing Classes:

FilterNode.NodeAdapter, NodeAdapter, WeakListener.Node

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.

Method Summary

void	childrenAdded(NodeMemberEvent ev) Fired when a set of new children is added.
void	childrenRemoved(NodeMemberEvent ev) Fired when a set of children is removed.
void	childrenReordered(NodeReorderEvent ev) Fired when the order of children is changed.
void	nodeDestroyed(NodeEvent ev) Fired when the node is deleted.
