- * 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.
