,org.reactivestreams.Subscriber<T>
,org.reactivestreams.Subscription
public class StrictSubscriber<T> extends java.util.concurrent.atomic.AtomicInteger implements FlowableSubscriber<T>, org.reactivestreams.Subscription
Ensures that the event flow between the upstream and downstream follow the Reactive-Streams 1.0 specification by honoring the 3 additional rules (which are omitted in standard operators due to performance reasons).- §1.3: onNext should not be called concurrently until onSubscribe returns
- §2.3: onError or onComplete must not call cancel
- §3.9: negative requests should emit an onError(IllegalArgumentException)
- Since:
- 2.0.7

Description copied from interface:FlowableSubscriber
Implementors of this method should make sure everything that needs to be visible inSubscriber.onNext(Object)
is established before callingSubscription.request(long)
. In practice this means no initialization should happen after therequest()
call and additional behavior is thread safe in respect toonNext
