Class MergePreferred$

java.lang.Object

akka.stream.javadsl.MergePreferred$

public class MergePreferred$
extends java.lang.Object

Merge several streams, taking elements as they arrive from input streams (picking from preferred when several have elements ready).

'''Emits when''' one of the inputs has an element available, preferring a specified input if multiple have elements available

'''Backpressures when''' downstream backpressures

'''Completes when''' all upstreams complete (eagerComplete=false) or one upstream completes (eagerComplete=true)

'''Cancels when''' downstream cancels
