Class ElementKindVisitor9<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:
    ElementVisitor<R,P>

    @SupportedSourceVersion(RELEASE_9)
public class ElementKindVisitor9<R,P>
extends ElementKindVisitor8<R,P>
    A visitor of program elements based on their kind with default behavior appropriate for the RELEASE_9 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.

    Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with @Override will help ensure that methods are overridden as intended.

    WARNING: The ElementVisitor interface implemented by this class may have methods added to it or the ElementKind enum used in this case may have constants 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 "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 "visit".

    When such a new visit method is added, the default implementation in this class will be to call the visitUnknown method. A new abstract element kind 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.
