34 * A skeletal visitor of types with default behavior appropriate for

37 *
38 * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
39 * by this class may have methods added to it in the future to
40 * accommodate new, currently unknown, language structures added to
41 * future versions of the Java™ programming language.
42 * Therefore, methods whose names begin with {@code "visit"} may be
43 * added to this class in the future; to avoid incompatibilities,
44 * classes which extend this class should not declare any instance
45 * methods with names beginning with {@code "visit"}.
46 *
47 * <p>When such a new visit method is added, the default
48 * implementation in this class will be to call the {@link
49 * #visitUnknown visitUnknown} method. A new abstract type visitor
50 * class will also be introduced to correspond to the new language
51 * level; this visitor will have different default behavior for the
52 * visit method in question. When the new visitor is introduced, all
53 * or portions of this visitor may be deprecated.
54 *
55 * @param <R> the return type of this visitor's methods. Use {@link
56 * Void} for visitors that do not need to return results.
57 * @param <P> the type of the additional parameter to this visitor's
58 * methods. Use {@code Void} for visitors that do not need an
59 * additional parameter.
