38 * A simple visitor for annotation values with default behavior
39 * appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6}
40 * source version. Visit methods call {@link
41 * #defaultAction} passing their arguments to {@code defaultAction}'s
42 * corresponding parameters.
43 *
44 * <p> Methods in this class may be overridden subject to their
45 * general contract. Note that annotating methods in concrete
46 * subclasses with {@link java.lang.Override @Override} will help
47 * ensure that methods are overridden as intended.
48 *
49 * <p> <b>WARNING:</b> The {@code AnnotationValueVisitor} interface
50 * implemented by this class may have methods added to it in the
51 * future to accommodate new, currently unknown, language structures
52 * added to future versions of the Java™ programming language.
53 * Therefore, methods whose names begin with {@code "visit"} may be
54 * added to this class in the future; to avoid incompatibilities,
55 * classes which extend this class should not declare any instance
56 * methods with names beginning with {@code "visit"}.
57 *
58 * <p>When such a new visit method is added, the default
59 * implementation in this class will be to call the {@link
60 * #visitUnknown visitUnknown} method. A new simple annotation
61 * value visitor class will also be introduced to correspond to the
62 * new language level; this visitor will have different default
63 * behavior for the visit method in question. When the new visitor is
64 * introduced, all or portions of this visitor may be deprecated.
65 *
66 * @param <R> the return type of this visitor's methods
67 * @param <P> the type of the additional parameter to this visitor's methods.
