Class AbstractTypeVisitor7<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>
    Direct Known Subclasses:
    AbstractTypeVisitor8

    @SupportedSourceVersion(RELEASE_7)
public abstract class AbstractTypeVisitor7<R,P>
extends AbstractTypeVisitor6<R,P>
    A skeletal visitor of types with default behavior appropriate for the RELEASE_7 source version.

    WARNING: The TypeVisitor 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 "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 type 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.

    Since:
    1.7
