Interface PolyTreeTableUserObject

All Known Implementing Classes:

AbstractPolyTreeTableUserObject, FileTreeTable.FileTreeTableUserObject, Sample.FileTreeTableUserObject

public interface PolyTreeTableUserObject

A utility record that provides all methods necessary to be rendered generic in a TreeTable.
The DefaultTreeTableModel and DefaultPolyTreeNode implementations take note of the presence of this interface, which makes it possible to avoid overriding model and node classes (DefaultTreeTableModel, DefaultTreeNode). That means you are not obliged to implement subclasses of these classes to render table columns.

You need to implement equals() and hashCode(), as these nodes are managed in a Hashtable. Else there will be multiple appearances of one node.
