# Class TypeKindVisitor7<R,P>

java.lang.Object
javax.lang.model.util.AbstractTypeVisitor6<R,P>
javax.lang.model.util.SimpleTypeVisitor6<R,P>
javax.lang.model.util.TypeKindVisitor6<R,P>
javax.lang.model.util.TypeKindVisitor7<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>`

Direct Known Subclasses:
  `TypeKindVisitor8`

@SupportedSourceVersion(RELEASE_7) public class TypeKindVisitor7<R,P> extends TypeKindVisitor6<R,P>
A visitor of types based on their kind with default behavior appropriate for the `RELEASE_7` source version. For 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 `defaultAction`, passing their arguments to `defaultAction`'s corresponding parameters.

API Note:
  Methods in this class may be overridden subject to their general contract.
