Examples of org.reactivestreams.Subscription

org.reactivestreams.Subscription
A {@link Subscription} represents a one-to-one lifecycle of a {@link Subscriber} subscribing to a {@link Publisher}.
It can only be used once by a single {@link Subscriber}.
It is used to both signal desire for data and cancel demand (and allow resource cleanup).


    if (subscription == null) {
      return outboundStream;
    }


    Subscription sub = subscription;
    Action<?, ?> that = null;


    while (sub != null
        && PushSubscription.class.isAssignableFrom(sub.getClass())
        && ((PushSubscription<?>) sub).getPublisher() != null
        && Action.class.isAssignableFrom(((PushSubscription<?>) sub).getPublisher().getClass())
        ) {


      that = (Action<?, ?>) ((PushSubscription<?>) sub).getPublisher();
