Class MergeHub$


  • public class MergeHub$
    extends java.lang.Object
    Creates a Source that emits elements merged from a dynamic set of producers. After the Source returned by this method is materialized, it returns a Sink as a materialized value. This Sink can be materialized arbitrary many times and each of the materializations will feed the elements into the original Source.

    Every new materialization of the Source results in a new, independent hub, which materializes to its own Sink for feeding that materialization.

    Completed or failed Sinks are simply removed. Once the Source is cancelled, the Hub is considered closed and any new producers using the Sink will be cancelled.

    param: perProducerBufferSize Buffer space used per producer. Default value is 16.
