 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.

| static interface  | UIDefaults.ActiveValueThis class enables one to store an entry in the defaults
 table that's constructed each time it's looked up with one of
 the  getXXX(key)methods. |

get(uidClassID) must be the
 String name of a
 class that implements the corresponding ComponentUI
 class.  If the class hasn't been loaded before, this method looks
 up the class with uiClassLoader.loadClass() if a non
 null
 class loader is provided, classForName() otherwise.
 
 If a mapping for uiClassID exists or if the specified
 class can't be found, return null.
 
 This method is used by getUI, it's usually
 not necessary to call it directly.
