public class Visualizer

extends Object

This class provide access to thread safe layer that reflects the hierarchy of Nodes, but is updated only in event dispatch thread (in contrast to nodes that can be updated from any thread). That is why this class is useful for writers of explorer views, because it guarantees that all changes will be done safely.

NodeTreeModel, NodeListModel, etc. use these objects as its model values.
