null
only if the tree has no nodes.public Object getChild(Object parent, int index)
parent
at index index
in the parent's child array.
parent
must be a node previously obtained from this data source. This should not return
null
if index
is a valid index for parent
(that is index >= 0 && index
< getChildCount(parent
)).public int getChildCount(Object parent)
parent
. Returns 0 if the node is a leaf or if it has no children.
parent
must be a node previously obtained from this data source.getChildCount
in interface TreeModel
parent
- a node in the tree, obtained from this data sourceparent
public boolean isLeaf(Object node)
true
if node
is a leaf. It is possible for this method to return
false
even if node
has no children. A directory in a filesystem, for example, may contain
no files; the node representing the directory is not a leaf, but it also has no children.public void valueForPathChanged(TreePath path, Object newValue)
path
to newValue
.
If newValue
signifies a truly new value the model should post a treeNodesChanged

- path to the node that the user has alterednewValue
- the new value from the TreeCellEditorpublic int getIndexOfChild(Object parent, Object childNode)
parent

,
returns -1. If either parent
or child
don't belong to this tree model, returns -1.getIndexOfChild
