Class SimpleTypeVisitorPreview<R,P>

javax.lang.model.util.SimpleTypeVisitorPreview<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>

@SupportedSourceVersion(RELEASE_27) public class SimpleTypeVisitorPreview<R,P> extends SimpleTypeVisitor14<R,P>

SimpleTypeVisitorPreview 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 simple visitor of types with default behavior appropriate for a preview source version. Visit methods corresponding to RELEASE_14 and earlier language constructs call defaultAction, passing their arguments to defaultAction's corresponding parameters.

API Note:

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