Class SimpleAnnotationValueVisitor6<R,P>

  • Type Parameters:
    R - the return type of this visitor's methods
    P - the type of the additional parameter to this visitor's methods.
    All Implemented Interfaces:
    AnnotationValueVisitor<R,P>
    Direct Known Subclasses:
    SimpleAnnotationValueVisitor7


    @SupportedSourceVersion(value=RELEASE_6)
    public class SimpleAnnotationValueVisitor6<R,P>
    extends AbstractAnnotationValueVisitor6<R,P>
    A simple visitor for annotation values with default behavior appropriate for the RELEASE_6 source version. Visit methods call defaultAction(java.lang.Object, P) 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 AnnotationValueVisitor 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 simple annotation value 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.

    Note that adding a default implementation of a new visit method in a visitor class will occur instead of adding a default method directly in the visitor interface since a Java SE 8 language feature cannot be used to this version of the API since this version is required to be runnable on Java SE 7 implementations. Future versions of the API that are only required to run on Java SE 8 and later may take advantage of default methods in this situation.

    • Field Detail

      • DEFAULT_VALUE

        protected final R DEFAULT_VALUE
        Default value to be returned; defaultAction returns this value unless the method is overridden.
    • Constructor Detail

      • SimpleAnnotationValueVisitor6

        protected SimpleAnnotationValueVisitor6()
        Constructor for concrete subclasses; uses null for the default value.
      • SimpleAnnotationValueVisitor6

        protected SimpleAnnotationValueVisitor6(R defaultValue)
        Constructor for concrete subclasses; uses the argument for the default value.
        Parameters:
        defaultValue - the value to assign to DEFAULT_VALUE
    • Method Detail

      • defaultAction

        protected R defaultAction(Object o,

        The default action for visit methods. The implementation in this class just returns DEFAULT_VALUE; subclasses will commonly override this method.
        Parameters:

        DEFAULT_VALUE unless overridden
