All Implemented Interfaces:

BatchListener, DataSourceListener, java.util.EventListener, IlFreezableAdapter, TreeDSListener, javax.swing.event.TreeModelListener

Direct Known Subclasses:

IlDefaultJTreeAdapter

public abstract class IlAbstractJTreeAdapter

extends IlAbstractAdapter

implements TreeDSListener, javax.swing.event.TreeModelListener

This class adapts the events from the IlTreeDataSource to a Swing TreeModel. It does not implement how nodes are created or updated, that is, how the properties from the data source are mapped to the MutableTreeNode themselves. This class supports the mapping between the data source objects and the model objects. It stores the data source reference and delegates expansion or collapsing to the data source.
