java.lang.Objectjavax.lang.model.util.AbstractTypeVisitor6<R,P>
R
- the return type of this visitor's methods. Use Void
for visitors that do not need to return results.P
- the type of the additional parameter to this visitor's
methods. Use Void
for visitors that do not need an
additional parameter.public abstract class AbstractTypeVisitor6<R,P>
A skeletal visitor of types with default behavior appropriate for the version 6 language level.
WARNING: The 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 "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 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 the new visitor is introduced, all
or portions of this visitor may be deprecated.

. This behavior is not required of a
subclass.
