@SupportedSourceVersion(RELEASE_6) public class SimpleTypeVisitor6<R,P> extends AbstractTypeVisitor6<R,P>
RELEASE_6
source version.
Visit methods corresponding to RELEASE_6
language
constructs call defaultAction
, passing their
arguments to defaultAction
's corresponding parameters.
For constructs introduced in RELEASE_7
and later,
visitUnknown
is called instead.
Methods in this class may be overridden subject to their
general contract. Note that annotating methods in concrete
subclasses with @Override
will help
ensure that methods are overridden as intended.
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 simple 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.
