  34  * A visitor of types based on their {@linkplain TypeKind kind} with
  35  * default behavior appropriate for the {@link SourceVersion#RELEASE_6
  36  * RELEASE_6} source version.  For {@linkplain
  37  * TypeMirror types} <tt><i>XYZ</i></tt> that may have more than one
  38  * kind, the <tt>visit<i>XYZ</i></tt> methods in this class delegate
  39  * to the <tt>visit<i>XYZKind</i></tt> method corresponding to the
  40  * first argument's kind.  The <tt>visit<i>XYZKind</i></tt> methods
  41  * call {@link #defaultAction defaultAction}, passing their arguments
  42  * to {@code defaultAction}'s 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 TypeVisitor} interface implemented
  50  * by this class may have methods added to it in the future to
  51  * accommodate new, currently unknown, language structures added to
  52  * 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 type kind visitor class
