34 * A visitor of program elements based on their {@linkplain
35 * ElementKind kind} with default behavior appropriate for the {@link
36 * SourceVersion#RELEASE_7 RELEASE_7} source version. For {@linkplain
37 * Element elements} <code><i>Xyz</i></code> that may have more than one
38 * kind, the <code>visit<i>Xyz</i></code> methods in this class delegate
39 * to the <code>visit<i>Xyz</i>As<i>Kind</i></code> method corresponding to the
40 * first argument's kind. The <code>visit<i>Xyz</i>As<i>Kind</i></code> methods
41 * call {@link #defaultAction defaultAction}, passing their arguments
42 * to {@code defaultAction}'s 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 ElementVisitor} interface
50 * implemented by this class may have methods added to it or the
51 * {@code ElementKind} {@code enum} used in this case may have
52 * constants added to it in the future to accommodate new, currently
53 * unknown, language structures added to future versions of the
54 * Java™ programming language. Therefore, methods whose names
55 * begin with {@code "visit"} may be added to this class in the
56 * future; to avoid incompatibilities, classes which extend this class
57 * should not declare any instance methods with names beginning with
58 * {@code "visit"}.
59 *
60 * <p>When such a new visit method is added, the default
61 * implementation in this class will be to call the {@link
62 * #visitUnknown visitUnknown} method. A new abstract element kind
63 * visitor class will also be introduced to correspond to the new
64 * language level; this visitor will have different default behavior
65 * for the visit method in question. When the new visitor is
66 * introduced, all or portions of this visitor may be deprecated.
67 *
68 * @param <R> the return type of this visitor's methods. Use {@link
69 * Void} for visitors that do not need to return results.
70 * @param <P> the type of the additional parameter to this visitor's
71 * methods. Use {@code Void} for visitors that do not need an
72 * additional parameter.
73 *
