GraphStage

abstract class GraphStage[S <: Shape] extends GraphStageWithMaterializedValue[S, NotUsed]

A GraphStage represents a reusable graph stream processing stage. A GraphStage consists of a Shape which describes its input and output ports and a factory function that creates a GraphStageLogic which implements the processing logic that ties the ports together.
