* Applications can determine
* if an object supports the AccessibleValue interface by first
* obtaining its AccessibleContext (see
* {@link Accessible}) and then calling the
* {@link AccessibleContext#getAccessibleValue} method.
* If the return value is not null, the object supports this interface.
