getPathForEntry

public static Object[] getPathForEntry(TreeModel model,
                                       Object entry)

Get the path to a given entry in the tree model. If model is a DfcTreeModel, its getPathForEntry () method is used, otherwise uses inefficient generic algorithm.

cloneNodes

public static MutableTreeNode cloneNodes(TreeNode root)
                                  throws CloneNotSupportedException

Parameters:

root - The tree node to copy from.

Returns:

The root of the cloned node tree.

Throws:

CloneNotSupportedException

disposeNodes

public static void disposeNodes(TreeNode root)

Calls dispose on all Disposable nodes starting from a given root node.

dumpTree

public static void dumpTree(TreeModel tree,
                            PrintStream str)
