33/**
34 * A skeletal visitor of program elements with default behavior
35 * appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7}
36 * source version.
37 *
38 * <p> <b>WARNING:</b> The {@code ElementVisitor} interface
39 * implemented by this class may have methods added to it in the
40 * future to accommodate new, currently unknown, language structures
41 * added to future versions of the Java&trade; 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 element 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.
60 *
61 * @see AbstractElementVisitor6
62 * @see AbstractElementVisitor8
63 * @see AbstractElementVisitor9
64 * @since 1.7
