darcy@1054	33	* A simple visitor of types with default behavior appropriate for the
darcy@1054	34	* {@link SourceVersion#RELEASE_7 RELEASE_7} source version.
darcy@1054	35	*
darcy@1054	36	* Visit methods corresponding to {@code RELEASE_8} and earlier
darcy@1054	37	* language constructs call {@link #defaultAction defaultAction},
darcy@1054	38	* passing their arguments to {@code defaultAction}'s corresponding
darcy@1054	39	* parameters.
darcy@1054	40	*
darcy@1054	41	* <p> Methods in this class may be overridden subject to their
darcy@1054	42	* general contract. Note that annotating methods in concrete
darcy@1054	43	* subclasses with {@link java.lang.Override @Override} will help
darcy@1054	44	* ensure that methods are overridden as intended.
darcy@1054	45	*
darcy@1054	46	* <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
darcy@1054	47	* by this class may have methods added to it in the future to
darcy@1054	48	* accommodate new, currently unknown, language structures added to
darcy@1054	49	* future versions of the Java&trade; programming language.
darcy@1054	50	* Therefore, methods whose names begin with {@code "visit"} may be
darcy@1054	51	* added to this class in the future; to avoid incompatibilities,
darcy@1054	52	* classes which extend this class should not declare any instance
darcy@1054	53	* methods with names beginning with {@code "visit"}.
darcy@1054	54	*
darcy@1054	55	* <p>When such a new visit method is added, the default
darcy@1054	56	* implementation in this class will be to call the {@link
darcy@1054	57	* #visitUnknown visitUnknown} method. A new simple type visitor
darcy@1054	58	* class will also be introduced to correspond to the new language
darcy@1054	59	* level; this visitor will have different default behavior for the
darcy@1054	60	* visit method in question. When the new visitor is introduced, all
darcy@1054	61	* or portions of this visitor may be deprecated.
darcy@1054	62	*
darcy@1054	63	* @param <R> the return type of this visitor's methods. Use {@link
darcy@1054	64	* Void} for visitors that do not need to return results.
darcy@1054	65	* @param <P> the type of the additional parameter to this visitor's
darcy@1054	66	* methods. Use {@code Void} for visitors that do not need an
darcy@1054	67	* additional parameter.
darcy@1054	68	*
