abstract class GraphStage[S <: Shape] extends GraphStageWithMaterializedValue[S, NotUsed]
A GraphStage represents a reusable graph stream processing operator.
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.

addAttributes(attr: Attributes): Graph[S, NotUsed]
Add the given attributes to this Graph.
Add the given attributes to this Graph. If the specific attribute was already present on this graph this means the added attribute will be more specific than the existing one. If this Source is a composite of multiple graphs, new attributes on the composite will be less specific than attributes set directly on the individual graphs of the composite.
