35 * default behavior appropriate for source versions {@link
36 * SourceVersion#RELEASE_9 RELEASE_9} through {@link
37 * SourceVersion#RELEASE_12 RELEASE_12}.
38 *
39 * For {@linkplain
40 * TypeMirror types} <code><i>Xyz</i></code> that may have more than one
41 * kind, the <code>visit<i>Xyz</i></code> methods in this class delegate
42 * to the <code>visit<i>Xyz</i>As<i>Kind</i></code> method corresponding to the
43 * first argument's kind. The <code>visit<i>Xyz</i>As<i>Kind</i></code> methods
44 * call {@link #defaultAction defaultAction}, passing their arguments
45 * to {@code defaultAction}'s corresponding parameters.
46 *
47 * <p> Methods in this class may be overridden subject to their
48 * general contract. Note that annotating methods in concrete
49 * subclasses with {@link java.lang.Override @Override} will help
50 * ensure that methods are overridden as intended.

52 * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
53 * by this class may have methods added to it in the future to
54 * accommodate new, currently unknown, language structures added to
55 * future versions of the Java™ programming language.
56 * Therefore, methods whose names begin with {@code "visit"} may be
57 * added to this class in the future; to avoid incompatibilities,
60 *
61 * <p>When such a new visit method is added, the default
62 * implementation in this class will be to call the {@link
63 * #visitUnknown visitUnknown} method. A new type kind visitor class
64 * will also be introduced to correspond to the new language level;
65 * this visitor will have different default behavior for the visit
66 * method in question. When the new visitor is introduced, all or
67 * portions of this visitor may be deprecated.
68 *
69 * @param <R> the return type of this visitor's methods. Use {@link

71 * @param <P> the type of the additional parameter to this visitor's

73 * additional parameter.
