Hi, I'm starting to learn the basics of Akka Streams, and I have this :
final Source<Integer, NotUsed> source = Source.range(1, 100); final Sink<X, CompletionStage<Done>> sink = Sink.foreach(v -> System.out.println(v)); final Flow<X, Integer, NotUsed> flow = Flow.fromSinkAndSource(sink, source); What I'v read from the docs : Flow A processing stage which has *exactly one input and output*, which connects its up- and downstreams by transforming the data elements flowing through it. If I understand correctly, I could transform an Integer to an X. A map on flow doesn't work, since that requires an Integer to be returned. I tried : Flow<X, X, NotUsed> x = flow.map(v -> return new X() ); but then I can't materialize the flow using runWith, since it requires both a sink and a source (why ?? Since fromSinkAndSource already provided that). Can someone shed a light on this ?
