  34  * A skeletal visitor of types with default behavior appropriate for
  35  * source versions {@link SourceVersion#RELEASE_9 RELEASE_9} through
  36  * {@link SourceVersion#RELEASE_14 RELEASE_14}.
  37  *
  38  * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
  39  * by this class may have methods added to it in the future to
  40  * accommodate new, currently unknown, language structures added to
  41  * future versions of the Java&trade; programming language.
  42  * Therefore, methods whose names begin with {@code "visit"} may be
  43  * added to this class in the future; to avoid incompatibilities,
  44  * classes which extend this class should not declare any instance
  45  * methods with names beginning with {@code "visit"}.
  46  *
  47  * <p>When such a new visit method is added, the default
  48  * implementation in this class will be to call the {@link
  49  * #visitUnknown visitUnknown} method.  A new abstract type visitor
  50  * class will also be introduced to correspond to the new language
  51  * level; this visitor will have different default behavior for the
  52  * visit method in question.  When the new visitor is introduced, all
  53  * or portions of this visitor may be deprecated.
  54  *
  55  * @param <R> the return type of this visitor's methods.  Use {@link
  56  *            Void} for visitors that do not need to return results.
  57  * @param <P> the type of the additional parameter to this visitor's
  58  *            methods.  Use {@code Void} for visitors that do not need an
  59  *            additional parameter.
