+/**
+ * A simple visitor of types with default behavior appropriate for the
+ * {@link SourceVersion#RELEASE_9 RELEASE_9} source version.
+ *
+ * Visit methods corresponding to {@code RELEASE_9} and earlier
+ * language constructs call {@link #defaultAction defaultAction},
+ * passing their arguments to {@code defaultAction}'s corresponding
+ * parameters.
+ *
+ * <p> Methods in this class may be overridden subject to their
+ * general contract.  Note that annotating methods in concrete
+ * subclasses with {@link java.lang.Override @Override} will help
+ * ensure that methods are overridden as intended.
+ *
+ * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
+ * by this class may have methods added to it in the future to
+ * accommodate new, currently unknown, language structures added to
+ * future versions of the Java&trade; programming language.
+ * Therefore, methods whose names begin with {@code "visit"} may be
+ * added to this class in the future; to avoid incompatibilities,
+ * classes which extend this class should not declare any instance
+ * methods with names beginning with {@code "visit"}.
+ *
+ * <p>When such a new visit method is added, the default
+ * implementation in this class will be to call the {@link
+ * #visitUnknown visitUnknown} method.  A new simple type visitor
+ * class will also be introduced to correspond to the new language
+ * level; this visitor will have different default behavior for the
+ * visit method in question.  When the new visitor is introduced, all
+ * or portions of this visitor may be deprecated.
+ *
+ * @param <R> the return type of this visitor's methods.  Use {@link
+ *            Void} for visitors that do not need to return results.
+ * @param <P> the type of the additional parameter to this visitor's
+ *            methods.  Use {@code Void} for visitors that do not need an
+ *            additional parameter.
+ *
+ * @see SimpleTypeVisitor6
+ * @see SimpleTypeVisitor7
+ * @since 1.8
