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:

ElementVisitor<R,P>

@SupportedSourceVersion(RELEASE_27)
public class SimpleElementVisitorPreview<R,P>
extends SimpleElementVisitor14<R,P>

SimpleElementVisitorPreview 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 program elements 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.

Since:

23
