  31  * A skeletal visitor of types with default behavior appropriate for
  32  * the version 7 language level.

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