+/**
+ * A simple visitor for annotation values with default behavior
+ * appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6}
+ * source version. Visit methods call {@link
+ * #defaultAction} passing their arguments to {@code defaultAction}'s
+ * corresponding parameters.
+ *
+ *
Methods in this class may be overridden subject to their
+ * general contract. Note that annotating methods in concrete
+ * subclasses with {@link java.lang.Override @Override} will help
+ * ensure that methods are overridden as intended.
+ *
+ *
WARNING: The {@code AnnotationValueVisitor} interface
+ * implemented by this class may have methods added to it in the
+ * future to accommodate new, currently unknown, language structures
+ * added to future versions of the Java™ programming language.
+ * Therefore, methods whose names begin with {@code "visit"} may be
+ * added to this class in the future; to avoid incompatibilities,
+ * classes which extend this class should not declare any instance
+ * methods with names beginning with {@code "visit"}.
+ *
+ *
When such a new visit method is added, the default
+ * implementation in this class will be to call the {@link
+ * #visitUnknown visitUnknown} method. A new simple annotation
+ * value visitor class will also be introduced to correspond to the
+ * new language level; this visitor will have different default
+ * behavior for the visit method in question. When the new visitor is
+ * introduced, all or portions of this visitor may be deprecated.
+ *
+ *
Note that adding a default implementation of a new visit method
+ * in a visitor class will occur instead of adding a default
+ * method directly in the visitor interface since a Java SE 8
+ * language feature cannot be used to this version of the API since
+ * this version is required to be runnable on Java SE 7
+ * implementations. Future versions of the API that are only required
+ * to run on Java SE 8 and later may take advantage of default methods
+ * in this situation.
+ *
+ * @param the return type of this visitor's methods
+ * @param the type of the additional parameter to this visitor's methods.
