  34  * {@preview Associated with records, a preview feature of the Java language.
  35  *
  36  *           This class is associated with <i>records</i>, a preview
  37  *           feature of the Java language. Preview features
  38  *           may be removed in a future release, or upgraded to permanent
  39  *           features of the Java language.}
  40  *
  41  * A simple visitor of program elements with default behavior
  42  * appropriate for the {@link SourceVersion#RELEASE_14 RELEASE_14}
  43  * source version.
  44  *
  45  * Visit methods corresponding to {@code RELEASE_14} and earlier
  46  * language constructs call {@link #defaultAction defaultAction},
  47  * passing their arguments to {@code defaultAction}'s corresponding
  48  * parameters.
  49  *
  50  * <p> Methods in this class may be overridden subject to their
  51  * general contract.  Note that annotating methods in concrete
  52  * subclasses with {@link java.lang.Override @Override} will help
  53  * ensure that methods are overridden as intended.
  54  *
  55  * <p> <b>WARNING:</b> The {@code ElementVisitor} interface
  56  * implemented by this class may have methods added to it in the
  57  * future to accommodate new, currently unknown, language structures
  58  * added to future versions of the Java&trade; programming language.
  59  * Therefore, methods whose names begin with {@code "visit"} may be
  60  * added to this class in the future; to avoid incompatibilities,
  61  * classes which extend this class should not declare any instance
  62  * methods with names beginning with {@code "visit"}.
  63  *
  64  * <p>When such a new visit method is added, the default
  65  * implementation in this class will be to call the {@link
  66  * #visitUnknown visitUnknown} method.  A new simple element visitor
  67  * class will also be introduced to correspond to the new language
  68  * level; this visitor will have different default behavior for the
  69  * visit method in question.  When the new visitor is introduced, all
  70  * or portions of this visitor may be deprecated.
  71  *
  72  * @param <R> the return type of this visitor's methods.  Use {@code Void}
  73  *             for visitors that do not need to return results.
  74  * @param <P> the type of the additional parameter to this visitor's methods.  Use {@code Void}
  75  *              for visitors that do not need an additional parameter.
