abstract Object	getChild(Object parent, int index)
abstract int	getChildCount(Object parent)
abstract Class	getColumnClass(int column) Returns the type for column number column.
abstract int	getColumnCount() Returns the number ofs availible column.

abstract Object	getValueAt(Object node, int column) Returns the value to be displayed for node node, at column number column.
abstract boolean	isCellEditable(Object node, int column) Indicates whether the the value for node node, at column number column is editable.
boolean	isLeaf(Object node) Is this node a leaf?
void	removeTreeModelListener(TreeModelListener l) Removes a TreeModelListener from the list of listeners registered with this model.

getIndexOfChild

public int getIndexOfChild(Object parent,
                           Object child)

This method is not called by the current implementation of JTree. Implemented only for completion.

Specified by:

getIndexOfChild in interface TreeModel

addTreeModelListener

public void addTreeModelListener(TreeModelListener l)

Registers a new TreeModelListener with this model.

Specified by:

addTreeModelListener in interface TreeModel

removeTreeModelListener
