2015-11-26  Andrew John Hughes  <gnu_andrew@member.fsf.org>

	* javax/lang/model/util/AbstractAnnotationValueVisitor6.java:
	Fix missing brace in Javadoc.
	* javax/lang/model/util/AbstractAnnotationValueVisitor7.java:
	New abstract class.
	(AbstractAnnotationValueVisitor7()): Implemented.
	* javax/lang/model/util/AbstractElementVisitor7.java,
	New abstract class.
	(AbstractElementVisitor7()): Implemented.
	* javax/lang/model/util/AbstractTypeVisitor6.java:
	Fix missing brace in Javadoc.
	* javax/lang/model/util/AbstractTypeVisitor7.java:
	New abstract class.
	(AbstractTypeVisitor7()): Implemented.
	(visitUnion(UnionType,P)): Likewise.
	* javax/lang/model/util/ElementKindVisitor6.java:
	(visitVariableAsResourceVariable(VariableElement,P)):
	Should call visitUnknown for version 6.
	* javax/lang/model/util/ElementKindVisitor7.java:
	New class.
	(ElementKindVisitor7()): Implemented.
	(ElementKindVisitor7(R)): Likewise.
	(visitVariableAsResourceVariable(VariableElement,P)):
	Implemented to return the result of defaultAction.
	* javax/lang/model/util/ElementScanner6.java:
	Fix missing brace in Javadoc. Add missing @return
	documentation.
	(visitVariable(VariableElement,P)): Should call visitUnknown
	on 6 if the element is a resource variable element.
	* javax/lang/model/util/ElementScanner7.java,
	New class.
	(ElementScanner7()): Implemented.
	(ElementScanner7(R)): Likewise.
	(visitVariable(VariableElement,P)): Implemented.
	* javax/lang/model/util/SimpleAnnotationValueVisitor7.java:
	New class.
	(SimpleAnnotationValueVisitor7()): Implemented.
	(SimpleAnnotationValueVisitor7(R)): Likewise.
	* javax/lang/model/util/SimpleElementVisitor6.java:
	(visitVariable(VariableElement,P)): Should call visitUnknown
	on 6 if the element is a resource variable element.
	* javax/lang/model/util/SimpleElementVisitor7.java:
	New class.
	(SimpleElementVisitor7()): Implemented.
	(SimpleElementVisitor7(R)): Likewise.
	(visitVariable(VariableElement,P)): Implemented.
	* javax/lang/model/util/SimpleTypeVisitor6.java:
	(SimpleTypeVisitor6): Fix copy-and-paste error in documentation.
	* javax/lang/model/util/SimpleTypeVisitor7.java:
	New class.
	(SimpleTypeVisitor7()): Implemented.
	(SimpleTypeVisitor7(R)): Likewise.
	(visitUnion(UnionType,P)): Implemented.
	* javax/lang/model/util/TypeKindVisitor7.java,
	New class.
	(TypeKindVisitor7()): Implemented.
	(TypeKindVisitor7(R)): Likewise.
