21 * This adapter class provides default implementations for the
22 * methods described by the <code>AccessibleTextListener</code> interface.

28 * Note: Accessibility clients use child identifiers to specify
29 * whether they want information about a control or one of its children.
30 * Child identifiers are increasing integers beginning with 0.
31 * The identifier CHILDID_SELF represents the control itself.
32 * When returning a child identifier to a client, you may use CHILDID_NONE
33 * to indicate that no child or control has the required information.
34 * </p><p>
35 * Note: This adapter is typically used by implementors of
36 * a custom control to provide very detailed information about
37 * the control instance to accessibility clients.
