! * <p> Methods in this class may be overridden subject to their
! * general contract. Note that annotating methods in concrete

! * <p> <b>WARNING:</b> The {@code ElementVisitor} 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"}.
! *
! * <p>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 element scanner 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.

* @param <R> the return type of this visitor's methods. Use {@link
* Void} for visitors that do not need to return results.
* @param <P> the type of the additional parameter to this visitor's
* methods. Use {@code Void} for visitors that do not need an
* additional parameter.
