Class Broadcast


  • public class Broadcast
    extends java.lang.Object
    Fan-out the stream to several streams. emitting each incoming upstream element to all downstream consumers. It will not shutdown until the subscriptions for at least two downstream subscribers have been established.

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

    '''Backpressures when''' any of the outputs backpressure

    '''Completes when''' upstream completes

    '''Cancels when''' If eagerCancel is enabled: when any downstream cancels; otherwise: when all downstreams cancel
