javax.lang.model.util
Class TypeKindVisitor6<R,P>

java.lang.Object
  extended by javax.lang.model.util.AbstractTypeVisitor6<R,P>
      extended by javax.lang.model.util.SimpleTypeVisitor6<R,P>
          extended by javax.lang.model.util.TypeKindVisitor6<R,P>
Type Parameters:
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.
All Implemented Interfaces:
TypeVisitor<R,P>
@SupportedSourceVersion(value=RELEASE_6)
public class TypeKindVisitor6<R,P>
extends SimpleTypeVisitor6<R,P>

A visitor of types based on their kind with default behavior appropriate for the RELEASE_6 source version. For types XYZ that may have more than one kind, the visitXYZ methods in this class delegate to the visitXYZKind method corresponding to the first argument's kind. The visitXYZKind methods call 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 @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 type kind 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.

Since:
1.6
