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 abstract 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.
