35 * <P>The AccessibleExtendedText interface contains additional methods
36 * not provided by the AccessibleText interface
37 *
38 * Applications can determine if an object supports the AccessibleExtendedText
39 * interface by first obtaining its AccessibleContext (see {@link Accessible})
40 * and then calling the {@link AccessibleContext#getAccessibleText} method of
41 * AccessibleContext. If the return value is an instance of
42 * AccessibleExtendedText, the object supports this interface.
