  38  * A simple visitor for annotation values with default behavior
  39  * appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6}
  40  * source version.  Visit methods call {@link
  41  * #defaultAction} passing their arguments to {@code defaultAction}'s
  42  * 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 AnnotationValueVisitor} interface
  50  * implemented by this class may have methods added to it in the
  51  * future to accommodate new, currently unknown, language structures
  52  * added to future versions of the Java&trade; 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 simple annotation
  61  * value visitor class will also be introduced to correspond to the
  62  * new language level; this visitor will have different default
  63  * behavior for the visit method in question.  When the new visitor is
  64  * introduced, all or portions of this visitor may be deprecated.

  65  *
  66  * @param <R> the return type of this visitor's methods
  67  * @param <P> the type of the additional parameter to this visitor's methods.
