javax.lang.model.util.AbstractAnnotationValueVisitor6<R,P>

类型参数:

R - the return type of this visitor's methods

P - the type of the additional parameter to this visitor's methods.

@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.

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 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 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.

方法详细资料

visit

public final R visit(AnnotationValue av,
                     P p)

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

指定者:

visit 在接口中 AnnotationValueVisitor<R,P>

参数:

av - the value to visit

p - a visitor-specified parameter

返回:

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).

指定者:

visit 在接口中 AnnotationValueVisitor<R,P>

参数:

av - the value to visit

返回:

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.

The default implementation of this method in AbstractAnnotationValueVisitor6 will always throw UnknownAnnotationValueException. This behavior is not required of a subclass.

指定者:

visitUnknown 在接口中 AnnotationValueVisitor<R,P>

参数:

av - the unknown value being visited

p - a visitor-specified parameter

返回:

the result of the visit
