    1.40 + * A simple visitor for annotation values with default behavior
    1.41 + * appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7}
    1.42 + * source version.  Visit methods call {@link
    1.43 + * #defaultAction} passing their arguments to {@code defaultAction}'s
    1.44 + * corresponding parameters.
    1.45 + *
    1.46 + * <p> Methods in this class may be overridden subject to their
    1.47 + * general contract.  Note that annotating methods in concrete
    1.48 + * subclasses with {@link java.lang.Override @Override} will help
    1.49 + * ensure that methods are overridden as intended.
    1.50 + *
    1.51 + * <p> <b>WARNING:</b> The {@code AnnotationValueVisitor} interface
    1.52 + * implemented by this class may have methods added to it in the
    1.53 + * future to accommodate new, currently unknown, language structures
    1.54 + * added to future versions of the Java&trade; programming language.
    1.55 + * Therefore, methods whose names begin with {@code "visit"} may be
    1.56 + * added to this class in the future; to avoid incompatibilities,
    1.57 + * classes which extend this class should not declare any instance
    1.58 + * methods with names beginning with {@code "visit"}.
    1.59 + *
    1.60 + * <p>When such a new visit method is added, the default
    1.61 + * implementation in this class will be to call the {@link
    1.62 + * #visitUnknown visitUnknown} method.  A new simple annotation
    1.63 + * value visitor class will also be introduced to correspond to the
    1.64 + * new language level; this visitor will have different default
    1.65 + * behavior for the visit method in question.  When the new visitor is
    1.66 + * introduced, all or portions of this visitor may be deprecated.
    1.67 + *
    1.68 + * @param <R> the return type of this visitor's methods
    1.69 + * @param <P> the type of the additional parameter to this visitor's methods.
    1.70 + *
