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(RELEASE_26)
public class TypeKindVisitorPreview<R,P>
extends TypeKindVisitor14<R,P>

TypeKindVisitorPreview is a reflective preview API of the Java platform.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

A visitor of types based on their kind with default behavior appropriate for a preview 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.
