Class AbstractAnnotationValueVisitor6<R,P>

java.lang.Object

javax.lang.model.util.AbstractAnnotationValueVisitor6<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:

AbstractAnnotationValueVisitor7, SimpleAnnotationValueVisitor6

@SupportedSourceVersion(RELEASE_6)
public abstract class AbstractAnnotationValueVisitor6<R,P>
extends Object
implements AnnotationValueVisitor<R,P>

A skeletal visitor for annotation values with default behavior appropriate for the RELEASE_6 source version.

API Note:

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 and subclasses 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 directly or indirectly call the visitUnknown method. A new abstract 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 a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors.

Since:

1.6

Method Details

visit

public final R visit(AnnotationValue av,
 P p)

Visits any annotation value as if by passing itself to that value's accept. The invocation v.visit(av, p) is equivalent to av.accept(v, p).

Specified by:

visit in interface AnnotationValueVisitor<R,P>

Parameters:

av - the value to visit

p - a visitor-specified parameter

Returns:

a visitor-specified result

visit

public final R visit(AnnotationValue av)

Visits an annotation value as if by passing itself to that value's accept method passing null for the additional parameter. The invocation v.visit(av) is equivalent to av.accept(v, null).

Specified by:

visit in interface AnnotationValueVisitor<R,P>

Parameters:

av - the value to visit

Returns:

a visitor-specified result

visitUnknown

public R visitUnknown(AnnotationValue av,
 P p)

Visits an unknown kind of annotation value. This can occur if the language evolves and new kinds of value can be stored in an annotation.

Specified by:

visitUnknown in interface AnnotationValueVisitor<R,P>

Implementation Requirements:

The default implementation of this method in AbstractAnnotationValueVisitor6 will always throw new UnknownAnnotationValueException(av, p). This behavior is not required of a subclass.

Parameters:

av - the unknown value being visited

p - a visitor-specified parameter

Returns:

the result of the visit

Throws:

UnknownAnnotationValueException - a visitor implementation may optionally throw this exception
