Returns: Child.

getChildCount

public int getChildCount(Object parent)

Returns the number of children for the specified parent.

The specified parent must be a node previously obtained from this data source.

Parameters: parent A node in the tree, obtained from this data source.

Returns: The number of children of the specified parent, or 0 if the parent is a leaf node or if it has no children.

getIndexOfChild

public int getIndexOfChild(Object parent, Object child)

Returns the index of the specified child within the specified parent.

Parameters: parent Parent node. child Child node.

Returns: Index of child within parent.

getRoot

public Object getRoot()

Returns the root of the tree.

Returns: The root of the tree, or null if the tree has no nodes.

isLeaf

public boolean isLeaf(Object o)

Determines whether the specified tree node is a leaf node.

Parameters: o A node in the tree, obtained from this data source.

Returns: true if the node is a leaf; false otherwise.

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener l)

Removes a listener for TreeModelEvents.

Parameters: l The listener to remove.

valueForPathChanged
