SinkRefStageImpl

java.lang.Object
- akka.stream.stage.GraphStageWithMaterializedValue<SinkShape<In>,SourceRef<In>>
- - akka.stream.impl.streamref.SinkRefStageImpl<In>

All Implemented Interfaces:

Graph<SinkShape<In>,SourceRef<In>>
```
public final class SinkRefStageImpl<In>
extends GraphStageWithMaterializedValue<SinkShape<In>,SourceRef<In>>
```
INTERNAL API: Actual operator implementation backing SinkRefs.
If initialPartnerRef is set, then the remote side is already set up. If it is none, then we are the side creating the ref.
