Class FlowShape<I,O>

java.lang.Object

akka.stream.Shape

akka.stream.FlowShape<I,O>

All Implemented Interfaces:

java.io.Serializable, scala.Equals, scala.Product

public final class FlowShape<I,O>
extends Shape
implements scala.Product, scala.Serializable

A Flow Shape has exactly one input and one output, it looks from the outside like a pipe (but it can be a complex topology of streams within of course).
