WARNING: The {@code * TypeVisitor} 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 and subclasses 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 directly or indirectly call
* the {@link #visitUnknown visitUnknown} method. A new abstract type
* 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 a new visitor is
* introduced, portions of this visitor class may be deprecated,
* including its constructors.
*
* @param the type of the additional parameter to this visitor's
* methods. Use {@code Void} for visitors that do not need an
* additional parameter.
