org.apache.pekko.stream.javadsl.MergePrioritized

public class MergePrioritized
extends java.lang.Object

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

A MergePrioritized has one out port, one or more input port with their priorities.

'''Emits when''' one of the inputs has an element available, preferring a input based on its priority if multiple have elements available

'''Backpressures when''' downstream backpressures

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

'''Cancels when''' downstream cancels

A Broadcast has one in port and 2 or more out ports.
