WARNING: The {@code ElementVisitor} interface + * implemented by this class may have methods added to it in the + * future to accommodate new, currently unknown, language structures + * added to future versions of the Java™ programming language. + * Therefore, methods whose names begin with {@code "visit"} may be + * added to this class in the future; to avoid incompatibilities, + * classes which extend this class should not declare any instance + * methods with names beginning with {@code "visit"}. + * + *

When such a new visit method is added, the default + * implementation in this class will be to call the {@link + * #visitUnknown visitUnknown} method. A new abstract element visitor + * class will also be introduced to correspond to the new language + * level; this visitor will have different default behavior for the + * visit method in question. When the new visitor is introduced, all + * or portions of this visitor may be deprecated. + * + * @param the return type of this visitor's methods.

the type of the additional parameter to this visitor's + * methods. Use {@code Void} for visitors that do not need an + * additional parameter. + * + * @see AbstractElementVisitor6 + * @see AbstractElementVisitor7 + * @see AbstractElementVisitor8 + * @since 1.9 + */ +@SupportedSourceVersion(RELEASE_9) +public abstract class AbstractElementVisitor9 extends AbstractElementVisitor8 { + /** + * Constructor for concrete subclasses to call. + */ + protected AbstractElementVisitor9(){ + super(); + } +}
