Class SimpleAnnotationValueVisitor6<R,​P>

java.lang.Object
javax.lang.model.util.AbstractAnnotationValueVisitor6<R,​P>
javax.lang.model.util.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(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.

  • Field Details

    • DEFAULT_VALUE

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

  • Constructor Details

    • SimpleAnnotationValueVisitor6

      @Deprecated(since="9") protected SimpleAnnotationValueVisitor6()
      Deprecated.
      Release 6 is obsolete; update to a visitor for a newer release level.
      Constructor for concrete subclasses; uses null for the default value.

    • SimpleAnnotationValueVisitor6

      @Deprecated(since="9") protected SimpleAnnotationValueVisitor6​(R defaultValue)
      Deprecated.
      Release 6 is obsolete; update to a visitor for a newer release level.
      Constructor for concrete subclasses; uses the argument for the default value.
      Parameters:
      defaultValue - the value to assign to DEFAULT_VALUE

  • Method Details

    • defaultAction

      protected R defaultAction​(Object o, P p)
      The default action for visit methods.
      Implementation Requirements:

      Parameters:
      o - the value of the annotation
      p - a visitor-specified parameter
      Returns:
      DEFAULT_VALUE unless overridden
