Class 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.
