/**
* A visitor of types based on their {@linkplain TypeKind kind} with
* default behavior appropriate for the {@link SourceVersion#RELEASE_7
* RELEASE_7} source version. For {@linkplain
* TypeMirror types} Xyz
that may have more than one
* kind, the visitXyz
methods in this class delegate
* to the visitXyzAsKind
method corresponding to the
* first argument's kind. The visitXyzAsKind
methods
* call {@link #defaultAction defaultAction}, passing their arguments
* to {@code defaultAction}'s corresponding parameters.
*
*
Methods in this class may be overridden subject to their * general contract. Note that annotating methods in concrete * subclasses with {@link java.lang.Override @Override} will help * ensure that methods are overridden as intended. * *
WARNING: The {@code 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 {@code "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 {@code "visit"}. * *
When such a new visit method is added, the default
* implementation in this class will be to call the {@link
* #visitUnknown 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.
*
* @param the type of the additional parameter to this visitor's
* methods. Use {@code Void} for visitors that do not need an
* additional parameter.
*
* @see TypeKindVisitor6
* @see TypeKindVisitor8
