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.@SupportedSourceVersion(value=RELEASE_8) public class ElementKindVisitor8<R,P> extends ElementKindVisitor7<R,P>
RELEASE_8 source version.  For elements 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 ElementVisitor interface
 implemented by this class may have methods added to it or the
 ElementKind enum used in this case may have
 constants 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 abstract element 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.
 
Note that adding a default implementation of a new visit method in a visitor class will occur instead of adding a default method directly in the visitor interface since a Java SE 8 language feature cannot be used to this version of the API since this version is required to be runnable on Java SE 7 implementations. Future versions of the API that are only required to run on Java SE 8 and later may take advantage of default methods in this situation.
