Package Summary Overview Summary

### class:JTree.AccessibleJTree [NONE]
- All Implemented Interfaces: Serializable, EventListener, AccessibleComponent, AccessibleExtendedComponent, AccessibleSelection, TreeExpansionListener, TreeModelListener, TreeSelectionListener Enclosing class: JTree
      protected class JTree.AccessibleJTree
      extends JComponent.AccessibleJComponent
      implements AccessibleSelection, TreeSelectionListener, TreeModelListener, TreeExpansionListener
This class implements accessibility support for the `JTree` class. It provides an implementation of the Java Accessibility API appropriate to tree user-interface elements. 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 JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`.

### constructor:AccessibleJTree() [NONE]
