44 * <p> <b>WARNING:</b> The {@code AnnotationValueVisitor} interface
45 * implemented by this class may have methods added to it in the
46 * future to accommodate new, currently unknown, language structures
47 * added to future versions of the Java™ programming language.
48 * Therefore, methods whose names begin with {@code "visit"} may be
49 * added to this class in the future; to avoid incompatibilities,
50 * classes which extend this class should not declare any instance
51 * methods with names beginning with {@code "visit"}.
52 *
53 * <p>When such a new visit method is added, the default
54 * implementation in this class will be to call the {@link
55 * #visitUnknown visitUnknown} method. A new simple annotation
56 * value visitor class will also be introduced to correspond to the
57 * new language level; this visitor will have different default
58 * behavior for the visit method in question. When the new visitor is
59 * introduced, all or portions of this visitor may be deprecated.
60 *
61 * <p>Note that adding a default implementation of a new visit method
62 * in a visitor class will occur instead of adding a <em>default
63 * method</em> directly in the visitor interface since a Java SE 8
64 * language feature cannot be used to this version of the API since
65 * this version is required to be runnable on Java SE 7
66 * implementations. Future versions of the API that are only required
67 * to run on Java SE 8 and later may take advantage of default methods
68 * in this situation.
