Constructor Detail

SafeSubscriber

public SafeSubscriber(@NonNull
                      @NonNull org.reactivestreams.Subscriber<? super T> downstream)

Constructs a SafeSubscriber by wrapping the given actual Subscriber.

Method Detail

onSubscribe

public void onSubscribe(@NonNull
                        @NonNull org.reactivestreams.Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.
