    • load

      public S load()
      Loads this annotation description. This causes all classes referenced by the annotation value to be loaded. Without specifying a class loader, the annotation's class loader which was used to prepare this instance is used.
      Specified by:
      load in interface AnnotationDescription.Loadable<S extends Annotation>
      Returns:
      A loaded version of this annotation description.

    • asValue

      Extracts the annotation values of an annotation into a property map.
      Parameters:
      annotation - The annotation to convert.
      Returns:
      A mapping of property names to their annotation value.

    • asValue

      public static AnnotationValue<?,?> asValue(Object value, Class<?> type)
      Transforms an annotation property to an annotation value.
      Parameters:
      value - The annotations value.
      type - The annotation's type.
      Returns:
      An annotation value representation.

    • getValue

      public AnnotationValue<?,?> getValue(MethodDescription.InDefinedShape property)
      Returns a value of this annotation.
      Specified by:
      getValue in interface AnnotationDescription
      Parameters:
      property - The property being accessed.
      Returns:
      The value for the supplied property.

    • prepare

      public <T extends Annotation> AnnotationDescription.Loadable<T> prepare(Class<T> annotationType)
      Links this annotation description to a given annotation type such that it can be loaded. This does not cause the values of this annotation to be loaded.
      Specified by:
      prepare in interface AnnotationDescription
      Type Parameters:
      T - The type of the annotation.
      Parameters:
      annotationType - The loaded annotation type of this annotation description.
      Returns:
      A loadable version of this annotation description.

    • getAnnotationType

      public TypeDescription getAnnotationType()
      Returns a description of the annotation type of this annotation.
      Specified by:
      getAnnotationType in interface AnnotationDescription
      Returns:
      A description of the annotation type of this annotation.
