/**
* A simple visitor for annotation values with default behavior
* appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6}
* source version. Visit methods call {@link
* #defaultAction} passing their arguments to {@code defaultAction}'s
* corresponding parameters.
*
* @apiNote
* Methods in this class may be overridden subject to their general
* contract.
*
* WARNING: The {@code
* AnnotationValueVisitor} 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 programming language. Therefore, methods whose
* names begin with {@code "visit"} may be added to this class in the
* future; to avoid incompatibilities, classes and subclasses which
* extend this class should not declare any instance methods with
* names beginning with {@code "visit"}.
*
* When such a new visit method is added, the default
* implementation in this class will be to directly or indirectly call
* the {@link #visitUnknown visitUnknown} method. A new simple
* annotation value 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
* a new visitor is introduced, portions of this visitor class may be
* deprecated, including its constructors.
*
* @param the return type of this visitor's methods
* @param the type of the additional parameter to this visitor's methods.
