      • toOption

        public <T> scala.Option<T> toOption​(java.util.Optional<T> opt)
      • downcast

        public <A,​B1,​B2 extends B1> Marshaller<A,​B1> downcast​(Marshaller<A,​B2> m)
        Safe downcasting of the output type of the marshaller to a superclass.

        Marshaller is covariant in B, i.e. if B2 is a subclass of B1, then Marshaller[X,B2] is OK to use where Marshaller[X,B1] is expected.

        Parameters:
        m - (undocumented)
        Returns:
        (undocumented)
      • downcast

        public <A,​B1,​B2 extends B1> Marshaller<A,​B1> downcast​(Marshaller<A,​B2> m,
                                                                                java.lang.Class<B1> target)
        Safe downcasting of the output type of the marshaller to a superclass.

        Marshaller is covariant in B, i.e. if B2 is a subclass of B1, then Marshaller[X,B2] is OK to use where Marshaller[X,B1] is expected.

        Parameters:
        m - (undocumented)
        target - (undocumented)

      • optionMarshaller

        public <A> Marshaller<java.util.Optional<A>,​RequestEntity> optionMarshaller​(Marshaller<A,​RequestEntity> m)
        Marshals an Optional[A] to a RequestEntity an empty optional will yield an empty entity.
        Parameters:
        m - (undocumented)
        Returns:
        (undocumented)
      • oneOf

        public <A,​B> Marshaller<A,​B> oneOf​(scala.collection.immutable.Seq<Marshaller<A,​B>> ms)
        Helper for creating a "super-marshaller" from a number of "sub-marshallers". Content-negotiation determines, which "sub-marshaller" eventually gets to do the job.

        Please note that all passed in marshallers will actually be invoked in order to get the Marshalling object out of them, and later decide which of the marshallings should be returned. This is by-design, however in ticket as discussed in ticket https://github.com/akka/akka-http/issues/243 it MAY be changed in later versions of Akka HTTP.

        Parameters:
        ms - (undocumented)
        Returns:
        (undocumented)
