darcy@1054	32	/**
darcy@1054	33	* A simple visitor for annotation values with default behavior
darcy@1054	34	* appropriate for the {@link SourceVersion#RELEASE_8 RELEASE_8}
darcy@1054	35	* source version. Visit methods call {@link #defaultAction
darcy@1054	36	* defaultAction} passing their arguments to {@code defaultAction}'s
darcy@1054	37	* corresponding parameters.
darcy@1054	38	*
darcy@1054	39	* <p> Methods in this class may be overridden subject to their
darcy@1054	40	* general contract. Note that annotating methods in concrete
darcy@1054	41	* subclasses with {@link java.lang.Override @Override} will help
darcy@1054	42	* ensure that methods are overridden as intended.
darcy@1054	43	*
darcy@1054	44	* <p> <b>WARNING:</b> The {@code AnnotationValueVisitor} interface
darcy@1054	45	* implemented by this class may have methods added to it in the
darcy@1054	46	* future to accommodate new, currently unknown, language structures
darcy@1054	47	* added to future versions of the Java&trade; programming language.
darcy@1054	48	* Therefore, methods whose names begin with {@code "visit"} may be
darcy@1054	49	* added to this class in the future; to avoid incompatibilities,
darcy@1054	50	* classes which extend this class should not declare any instance
darcy@1054	51	* methods with names beginning with {@code "visit"}.
darcy@1054	52	*
darcy@1054	53	* <p>When such a new visit method is added, the default
darcy@1054	54	* implementation in this class will be to call the {@link
darcy@1054	55	* #visitUnknown visitUnknown} method. A new simple annotation
darcy@1054	56	* value visitor class will also be introduced to correspond to the
darcy@1054	57	* new language level; this visitor will have different default
darcy@1054	58	* behavior for the visit method in question. When the new visitor is
darcy@1054	59	* introduced, all or portions of this visitor may be deprecated.
darcy@1054	60	*
darcy@1522	61	* <p>Note that adding a default implementation of a new visit method
darcy@1522	62	* in a visitor class will occur instead of adding a <em>default
darcy@1522	63	* method</em> directly in the visitor interface since a Java SE 8
darcy@1522	64	* language feature cannot be used to this version of the API since
darcy@1522	65	* this version is required to be runnable on Java SE 7
darcy@1522	66	* implementations. Future versions of the API that are only required
darcy@1522	67	* to run on Java SE 8 and later may take advantage of default methods
darcy@1522	68	* in this situation.
darcy@1522	69	*
darcy@1054	70	* @param <R> the return type of this visitor's methods
darcy@1054	71	* @param <P> the type of the additional parameter to this visitor's methods.
