javassist.bytecode.ParameterAnnotationsAttribute
public class ParameterAnnotationsAttribute
A class representing 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.

public ParameterAnnotationsAttribute(ConstPool cp,
java.lang.String attrname,
byte[] info)
Runtime(In)VisisbleParameterAnnotations_attribute.
cp - constant poolattrname - attribute name (visibleTag or
invisibleTag).info - the contents of this attribute. It does not
include attribute_name_index or
attribute_length.
public ParameterAnnotationsAttribute(ConstPool cp,
java.lang.String attrname)
Runtime(In)VisisbleParameterAnnotations_attribute.
A new annotation can be later added to the created attribute
by setAnnotations().
