Class Merge


  • public class Merge
    extends java.lang.Object
    Merge several streams, taking elements as they arrive from input streams (picking randomly when several have elements ready).

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

    '''Backpressures when''' downstream backpressures

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

    '''Cancels when''' downstream cancels
