      No longer needs to be instantiated directly, just use the static methods
      Constructs a new writer for the given class name and metadata.
      Parameters:
      className - The class name for which the metadata relates
      originatingElement - The originating element
      annotationMetadata - The annotation metadata
      writeAnnotationDefaults - Whether annotations defaults should be written
