Value Members
- def addAttributes(attr: Attributes): RunnableGraph[Mat]
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.

- Implicit
- This member is added by an implicit conversion from RunnableGraph[Mat] toGraphMapMatVal[ClosedShape, Mat] performed by method GraphMapMatVal in akka.stream.Graph.
- Shadowing
- This implicitly inherited member is shadowed by one or more members in this class.
To access this member you can use a type ascription:(runnableGraph: GraphMapMatVal[ClosedShape, Mat]).mapMaterializedValue(f)
