34 * A visitor of types based on their {@linkplain TypeKind kind} with
35 * default behavior appropriate for the {@link SourceVersion#RELEASE_6
36 * RELEASE_6} source version. For {@linkplain
37 * TypeMirror types} <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>XYZKind</i></code> method corresponding to the
40 * first argument's kind. The <code>visit<i>XYZKind</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 TypeVisitor} interface implemented
50 * by this class may have methods added to it in the future to
51 * accommodate new, currently unknown, language structures added to
52 * 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 type kind visitor class
61 * will also be introduced to correspond to the new language level;
62 * this visitor will have different default behavior for the visit
63 * method in question. When the new visitor is introduced, all or
64 * portions of this visitor may be deprecated.
65 *
66 * <p>Note that adding a default implementation of a new visit method
67 * in a visitor class will occur instead of adding a <em>default
68 * method</em> directly in the visitor interface since a Java SE 8
69 * language feature cannot be used to this version of the API since
70 * this version is required to be runnable on Java SE 7
71 * implementations. Future versions of the API that are only required
72 * to run on Java SE 8 and later may take advantage of default methods
73 * in this situation.
74 *
75 * @param <R> the return type of this visitor's methods. Use {@link
76 * Void} for visitors that do not need to return results.
77 * @param <P> the type of the additional parameter to this visitor's
78 * methods. Use {@code Void} for visitors that do not need an
79 * additional parameter.
