    • Method Detail

      • sink

        public static <T> Sink<T,​Source<T,​NotUsed>> sink()
        Creates a Sink that receives elements from its upstream producer and broadcasts them to a dynamic set of consumers. After the Sink returned by this method is materialized, it returns a Source as materialized value. This Source can be materialized arbitrary many times and each materialization will receive the broadcast elements from the original Sink.

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

        If the original Sink is failed, then the failure is immediately propagated to all of its materialized Sources (possibly jumping over already buffered elements). If the original Sink is completed, then all corresponding Sources are completed. Both failure and normal completion is "remembered" and later materializations of the Source will see the same (failure or completion) state. Sources that are cancelled are simply removed from the dynamic set of consumers.
