RELEASE_6
source version.
WARNING: The 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 "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 "visit".
When such a new visit method is added, the default
implementation in this class will be to call the visitUnknown method. A new abstract element 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.
