  17. def pumpSourceIntoStreamObserver[T](in: Source[T, _], destination: StreamObserver[T])(implicit materializer: Materializer): Unit

    Represents an akka source as Stream Observer.

  18. def respondMultiInSingleOutWithHeader[Input, Output](errorHandler: PartialFunction[Throwable, Throwable], responseObserver: StreamObserver[Output])(f: (Input, Source[Input, _]) ⇒ Future[Output])(implicit materializer: Materializer, ec: ExecutionContext): StreamObserver[Input]

    Helper to implement streamy input functions with special treating for the first (header) element.

    Helper to implement streamy input functions with special treating for the first (header) element.

    The function f is called with the first element and the source of ALL elements (including the first)

    f is allowed to block, but not too long.

    errorHandler

    an error handling function.

    f

    handler function

    returns

    a A Stream Observer which handles the input type.

  19. def respondMultiOut[Output](errorHandler: PartialFunction[Throwable, Throwable], responseObserver: StreamObserver[Output], source: Source[Output, _])(implicit materializer: Materializer): Unit

    Respond to a multi out request.

  20. def singleStreamObserverFuture[T](): (StreamObserver[T], Future[T])

    Generates a StreamObserver, which takes a single element and puts it into a future.

  21. def sinkFromStreamObserver[T](destination: StreamObserver[T]): Sink[T, NotUsed]

    Generates a Sink which forwards all to the given stream observer.

  22. def sinkFromStreamObserverWithSpecialHandling[U, T, S](destination: StreamObserver[T], f: (U) ⇒ T, g: (U) ⇒ T, completer: (Unit) ⇒ Option[T] = _: Unit => None, initialState: S, stateUpdate: (S, T) ⇒ S): Sink[U, Future[S]]

    Generates a Sink from a stream observer with special handling for the first element.

    Generates a Sink from a stream observer with special handling for the first element.

    U

    sink type

    T

    observer type

    S

    state type (from observer type)

    f

    function used for the first element.

    g

    function used for the rest of the elements.

    completer

    function used when the stream is complete

  23. def splitFirst[T](f: (Try[T]) ⇒ StreamObserver[T]): StreamObserver[T]

    Build a stream observer, which splits the first element and calls f, which in turn creates an StreamObserver which is used for the rest of the objects

  24. def streamObserverCollector[T](): (StreamObserver[T], Future[Vector[T]])

    Generates a stream observer which collects many elements into a vector.

    Generates a stream observer which collects many elements into a vector. Do not use in production.

  25. def streamObserverSource[T](bufSize: Int = 1): Source[T, StreamObserver[T]]

    Generates a source which materializes to a Stream Observer.
