public class ParameterAnnotationsAttribute extends AttributeInfo
RuntimeVisibleAnnotations_attribute
and
RuntimeInvisibleAnnotations_attribute
.
To obtain an ParameterAnnotationAttribute object, invoke
getAttribute(ParameterAnnotationsAttribute.invisibleTag)
in MethodInfo
.
The obtained attribute is a
runtime invisible annotations attribute.
If the parameter is
ParameterAnnotationAttribute.visibleTag
, then the obtained
attribute is a runtime visible one.
