A simple visitor of types with default behavior appropriate for the SourceVersion#RELEASE_9 RELEASE_
9 source version. Visit methods corresponding to RELEASE_9 and earlier language constructs call #defaultAction defaultAction, passing their arguments to defaultAction's corresponding parameters.
Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with java.lang.Override @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 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. @param the return type of this visitor's methods. Use Void for visitors that do not need to return results. @param the type of the additional parameter to this visitor's methods. Use Void for visitors that do not need an additional parameter. @see SimpleTypeVisitor6 @see SimpleTypeVisitor7 @since 9
