@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.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 and subclasses 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 directly or indirectly 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 a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors.
