  36  * A skeletal visitor for annotation values with default behavior

  40  * @apiNote
  41  * <p id=note_for_subclasses><strong>WARNING:</strong> The {@code
  42  * AnnotationValueVisitor} interface implemented by this class may
  43  * have methods added to it in the future to accommodate new,
  44  * currently unknown, language structures added to future versions of
  45  * the Java&trade; programming language.  Therefore, methods whose
  46  * names begin with {@code "visit"} may be added to this class in the
  47  * future; to avoid incompatibilities, classes and subclasses which
  48  * extend this class should not declare any instance methods with
  49  * names beginning with {@code "visit"}.</p>
  50  *
  51  * <p>When such a new visit method is added, the default
  52  * implementation in this class will be to directly or indirectly call
  53  * the {@link #visitUnknown visitUnknown} method.  A new abstract
  54  * annotation value visitor class will also be introduced to
  55  * correspond to the new language level; this visitor will have
  56  * different default behavior for the visit method in question.  When
  57  * a new visitor is introduced, portions of this visitor class may be
  58  * deprecated, including its constructors.
  59  *
  60  * @param <R> the return type of this visitor's methods
  61  * @param <P> the type of the additional parameter to this visitor's methods.
