39 * features of the Java language.}

44 *
45 * <p> <b>WARNING:</b> The {@code ElementVisitor} interface
46 * implemented by this class may have methods added to it in the
47 * future to accommodate new, currently unknown, language structures
48 * added to future versions of the Java™ programming language.
49 * Therefore, methods whose names begin with {@code "visit"} may be
50 * added to this class in the future; to avoid incompatibilities,
51 * classes which extend this class should not declare any instance
52 * methods with names beginning with {@code "visit"}.
53 *
54 * <p>When such a new visit method is added, the default
55 * implementation in this class will be to call the {@link
56 * #visitUnknown visitUnknown} method. A new abstract element visitor
57 * class will also be introduced to correspond to the new language
58 * level; this visitor will have different default behavior for the
59 * visit method in question. When the new visitor is introduced, all
60 * or portions of this visitor may be deprecated.
61 *
62 * @param <R> the return type of this visitor's methods. Use {@link
63 * Void} for visitors that do not need to return results.
64 * @param <P> the type of the additional parameter to this visitor's
65 * methods. Use {@code Void} for visitors that do not need an
66 * additional parameter.
