Interface PolyTreeTableModel

All Known Implementing Classes:

AbstractPolyTreeTableModel

public interface PolyTreeTableModel

The data model for PolyTreeTable that holds a polyhierarchy.
The TreeModel interface is rewritten here because of following reasons:

• TreePath does not satisfy the needs of navigation in a structure that allows cycles.
• The TreeModelListener interface is messaged using TreePath.
• The basic methods of TreeModel contain names that are ambigous or useless for the needs of PolyTreeTableModel: isLeaf(), getRoot().

Nevertheless most method names of PolyTreeTableModel match those of TreeModel and implement the same semantics.
