Preview

Language Model preview API.

ElementKindVisitorPreview 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 program elements based on their kind with default behavior appropriate for a preview source version. For elements 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.
