      protected void subscribeActual(org.reactivestreams.Subscriber<? super R> s)
      Description copied from class: Flowable
      Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

      There is no need to call any of the plugin hooks on the current Flowable instance or the Subscriber; all hooks and basic safeguards have been applied by Flowable.subscribe(Subscriber) before this method gets called.

      Specified by:
      subscribeActual in class Flowable<R>
      Parameters:
      s - the incoming Subscriber, never null
    • subscribe

      public static <T, R> org.reactivestreams.Subscriber<T> subscribe(org.reactivestreams.Subscriber<? super R> downstream, Function<? super T,? extends Stream<? extends R>> mapper, int prefetch)
      Create a Subscriber with the given parameters.
      Type Parameters:
      T - the upstream value type
      R - the Stream and output value type
      Parameters:
      downstream - the downstream Subscriber to wrap
      mapper - the mapper function
      prefetch - the number of items to prefetch
      Returns:
      the new Subscriber
