public final class SameAnnotationValueVisitor extends AbstractAnnotationValueVisitor14<Boolean,Object>
An AbstractAnnotationValueVisitor14 that determines if the otherwise opaque values represented by two AnnotationValue implementations are to be considered the same.

This class implements the rules described by the Annotation.equals(Object) contract, for want of a more authoritative source. This contract appears to define in a mostly agnostic manner what it means for two annotations to be "the same".

Unlike some other annotation-processing-related facilities, the relation represented by this SameAnnotationValueVisitor does not require that the values being logically compared originate from AnnotationValue instances from the same vendor or toolkit.

The second argument passed to AbstractAnnotationValueVisitor6.visit(AnnotationValue, Object) is expected to be either null, an AnnotationValue, or the result of an invocation of an AnnotationValue's getValue() method.

Any two TypeElements encountered during traversal are considered equal if their qualified names have equal contents.

Any two VariableElements representing enum constants encountered during traversal are considered equal if they belong to the same enum class and their simple names have equal contents.
