.. _-rejectEmptyResponse-java-: rejectEmptyResponse =================== Description ----------- Replaces a response with no content with an empty rejection. The ``rejectEmptyResponse`` directive is mostly used with marshalling ``Option[T]`` instances. The value ``None`` is usually marshalled to an empty but successful result. In many cases ``None`` should instead be handled as ``404 Not Found`` which is the effect of using ``rejectEmptyResponse``.
