public class TreeNodeAdapter
extends AbstractTreeNode

This class is a wrapper element for any Object that should be linked into a tree data structure as represented by AbstractTreeNode, but that might by itself not be an instance of TreeNode, i.e., not compatible with the remaining tree data structure. In analogy to MutableTreeNode we call this Object userObject (see getUserObject() and setUserObject(Object)).

This wrapper distinguishes the following special cases depending on the type of userObject when accessing the i^th child of this TreeNode. The userObject is an instance of

• TreeNode: recursive operations are continued at this element
• Collection: recursion leads to the i^th element in the Iterator
• Map: the key set is sorted (only possible if the keys implement the Comparable interface) and recursion continues at the i^th key.

Constructor Detail

TreeNodeAdapter

public TreeNodeAdapter(java.lang.Object userObject,
                       javax.swing.tree.TreeNode parent)

Creates a new TreeNode wrapper for the given userObject that will be linked to the given AbstractTreeNode.parent within an exisiting tree.

Parameters:

userObject - the element to be wrapped in a TreeNode; may be null.

parent - the parent TreeNode of this new node, i.e., the position within an existing tree where to link this new node. May be null.

TreeNodeAdapter

public TreeNodeAdapter(TreeNodeAdapter node)

Copy constructor for the given node. Note that the pointer to the parent will not be cloned.

Parameters:

node -
