  org.jppf.ui.treetable.AbstractTreeTableModel
      org.jppf.ui.treetable.FileSystemModel

All Implemented Interfaces:

TreeModel, TreeTableModel

public class FileSystemModel
extends AbstractTreeTableModel
implements TreeTableModel

FileSystemModel is a TreeTableModel representing a hierarchical file system. Nodes in the FileSystemModel are FileNodes which, when they are directory nodes, cache their children to avoid repeatedly querying the real file system.
