All Implemented Interfaces:

AnnotationValueVisitor

public class SimpleAnnotationValueVisitor6
extends AbstractAnnotationValueVisitor6

A simple visitor for annotation values with default behavior appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6} source version. Visit methods call {@link #defaultAction} passing their arguments to {@code defaultAction}'s corresponding parameters.

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

WARNING: The {@code 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 {@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 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.

DEFAULT_VALUE

protected final Object DEFAULT_VALUE

Default value to be returned; {@link #defaultAction defaultAction} returns this value unless the method is overridden.

SimpleAnnotationValueVisitor6

protected SimpleAnnotationValueVisitor6()

Constructor for concrete subclasses; uses {@code null} for the default value.

SimpleAnnotationValueVisitor6

protected SimpleAnnotationValueVisitor6(Object defaultValue)

Constructor for concrete subclasses; uses the argument for the default value.

Parameters:

defaultValue - the value to assign to {@link #DEFAULT_VALUE}

defaultAction

protected Object defaultAction(Object o,
                               Object p)

The default action for visit methods. The implementation in this class just returns {@link #DEFAULT_VALUE}; subclasses will commonly override this method.

Parameters:

o - the value of the annotation

p - a visitor-specified parameter

Returns:

{@code DEFAULT_VALUE} unless overridden
