java.lang.Objectjavassist.bytecode.AttributeInfo
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.

---|---|
static java.lang.String |
invisibleTag
The name of the RuntimeInvisibleParameterAnnotations
attribute. |
static java.lang.String |
visibleTag
The name of the RuntimeVisibleParameterAnnotations
attribute. |
