All Implemented Interfaces:
Cloneable, MutableTreeNode, Serializable, TreeNode
Enclosing class:
JTree
public static class JTree.DynamicUtilTreeNode
extends DefaultMutableTreeNode

DynamicUtilTreeNode can wrap vectors/hashtables/arrays/strings and create the appropriate children tree nodes as necessary. It is dynamic in that it will only create the children as necessary.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
