public class ExplorerTreeModel

extends javax.swing.tree.DefaultTreeModel

implements TreeModelUMLEventListener, java.awt.event.ItemListener

The model for the Explorer tree view of the uml model. provides: - receives events from the uml model and updates itself and the tree ui. - responds to changes in perspetive and ordering.
