Method Detail

getChild

public Object getChild(Object parent,
                       int index)

Returns the child of 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)).

Specified by:

getChild in interface TreeModel

Overrides:

getChild in class DefaultTreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the child of parent at index index

getChildCount

public int getChildCount(Object parent)

Returns the number of children of 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.

Specified by:

getChildCount in interface TreeModel

Overrides:

getChildCount in class DefaultTreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the number of children of the node parent

getIndexOfChild

public int getIndexOfChild(Object parent,
                           Object child)

Returns the index of child in parent. If parent is null or child is null, returns -1.

Specified by:

getIndexOfChild in interface TreeModel

Overrides:

getIndexOfChild in class DefaultTreeModel

Parameters:

parent - a note in the tree, obtained from this data source

child - the node we are interested in

Returns:

the index of the child in the parent, or -1 if either child or parent are null

getRoot

public Object getRoot()

Returns the root of the tree. Returns null only if the tree has no nodes.

Specified by:

getRoot in interface TreeModel

Overrides:

getRoot in class DefaultTreeModel

Returns:

the root of the tree

isLeaf

public boolean isLeaf(Object node)

Returns 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.

Specified by:

isLeaf in interface TreeModel

Overrides:

isLeaf in class DefaultTreeModel

Parameters:

node - a node in the tree, obtained from this data source

Returns:

true if node is a leaf

valueForPathChanged

public void valueForPathChanged(TreePath path,
                                Object newValue)

Specified by:

valueForPathChanged in interface TreeModel

Overrides:

valueForPathChanged in class DefaultTreeModel
