Class Partition$


  • public class Partition$
    extends java.lang.Object
    Fan-out the stream to several streams. emitting an incoming upstream element to one downstream consumer according to the partitioner function applied to the element

    Adheres to the ActorAttributes.SupervisionStrategy attribute.

    '''Emits when''' all of the outputs stops backpressuring and there is an input element available

    '''Backpressures when''' one of the outputs backpressure

    '''Completes when''' upstream completes

    '''Cancels when''' when any (eagerCancel=true) or all (eagerCancel=false) of the downstreams cancel
