Class ZipWithN<A,O>

java.lang.Object

akka.stream.stage.GraphStageWithMaterializedValue<S,NotUsed>

akka.stream.stage.GraphStage<UniformFanInShape<A,O>>

akka.stream.scaladsl.ZipWithN<A,O>

All Implemented Interfaces:

Graph<UniformFanInShape<A,O>,NotUsed>

Direct Known Subclasses:

ZipN

public class ZipWithN<A,O>
extends GraphStage<UniformFanInShape<A,O>>

Combine the elements of multiple streams into a stream of sequences using a combiner function.

A ZipWithN has a n input ports and one out port

'''Emits when''' all of the inputs has an element available

'''Backpressures when''' downstream backpressures

'''Completes when''' any upstream completes

'''Cancels when''' downstream cancels
