Class AnnotatedParameter


public final class AnnotatedParameter extends AnnotatedMember
Object that represents method parameters, mostly so that associated annotations can be processed conveniently. Note that many of accessors can not return meaningful values since parameters do not have stand-alone JDK objects associated; so access should mostly be limited to checking annotation values which are properly aggregated and included.

Note: as of version 1.7, this type extends AnnotatedMember, since it behaves like a member for the most part, but earlier it just extended Annotated

    • withAnnotations

      public AnnotatedParameter withAnnotations(AnnotationMap ann)
      Description copied from class: Annotated
      Fluent factory method that will construct a new instance that uses specified instance annotations instead of currently configured ones.
      Specified by:
      withAnnotations in class Annotated
    • addOrOverride

      public void addOrOverride(Annotation a)
    • getAnnotated

      public AnnotatedElement getAnnotated()
      Since there is no matching JDK element, this method will always return null
      Specified by:
      getAnnotated in class Annotated
    • getModifiers

      public int getModifiers()
      Returns modifiers of the constructor, as parameters do not have independent modifiers.
      Specified by:
      getModifiers in class Annotated
    • getName

      public String getName()
      Parameters have no names in bytecode (unlike in source code), will always return empty String ("").
      Specified by:
      getName in class Annotated
    • getAnnotation

      public <A extends Annotation> A getAnnotation(Class<A> acls)
      Accessor for annotations; all annotations associated with parameters are properly passed and accessible.
      Specified by:
      getAnnotation in class Annotated
    • getGenericType

      public Type getGenericType()
      Description copied from class: Annotated
      Full generic type of the annotated element; definition of what exactly this means depends on sub-class.
      Specified by:
      getGenericType in class Annotated
    • getRawType

      public Class<?> getRawType()
      Description copied from class: Annotated
      "Raw" type (type-erased class) of the annotated element; definition of what exactly this means depends on sub-class.
      Specified by:
      getRawType in class Annotated
    • getDeclaringClass

      public Class<?> getDeclaringClass()
      Specified by:
      getDeclaringClass in class AnnotatedMember
    • getMember

      public Member getMember()
      Specified by:
      getMember in class AnnotatedMember
    • setValue

      public void setValue(Object pojo, Object value) throws UnsupportedOperationException
      Description copied from class: AnnotatedMember
      Optional method that can be used to assign value of this member on given object, if this is a supported operation for member type.

      This is implemented for fiedlds and single-argument methods; but not for constructor parameters or other types of methods.

      Specified by:
      setValue in class AnnotatedMember
      Throws:
      UnsupportedOperationException
    • getParameterType

      public Type getParameterType()
