  56  * This class is used to handle the transfer of a <code>Transferable</code>
  57  * to and from Swing components.  The <code>Transferable</code> is used to
  58  * represent data that is exchanged via a cut, copy, or paste
  59  * to/from a clipboard.  It is also used in drag-and-drop operations
  60  * to represent a drag from a component, and a drop to a component.
  61  * Swing provides functionality that automatically supports cut, copy,
  62  * and paste keyboard bindings that use the functionality provided by
  63  * an implementation of this class.  Swing also provides functionality
  64  * that automatically supports drag and drop that uses the functionality
  65  * provided by an implementation of this class.  The Swing developer can
  66  * concentrate on specifying the semantics of a transfer primarily by setting
  67  * the <code>transferHandler</code> property on a Swing component.
  68  * <p>
  69  * This class is implemented to provide a default behavior of transferring
  70  * a component property simply by specifying the name of the property in
  71  * the constructor.  For example, to transfer the foreground color from
