Implements abstract io.reactivex.Flowable.subscribeActual.

Doc from io.reactivex.Flowable.subscribeActual.

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 subscribe(Subscriber) before this method gets called.

Parameters
s:Subscriber<? super U>

the incoming Subscriber, never null

the element signaled

Annotations
@Override
onSubscribeback to summary
public void onSubscribe(Subscription s)

Implements io.reactivex.FlowableSubscriber.onSubscribe.

Doc from io.reactivex.FlowableSubscriber.onSubscribe.

Implementors of this method should make sure everything that needs to be visible in 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. Invoked after calling Publisher#subscribe(Subscriber).

No data will start flowing until Subscription#request(long) is invoked.

It is the responsibility of this Subscriber instance to call Subscription#request(long) whenever more data is wanted.

The Publisher will send notifications only in response to Subscription#request(long).

Parameters
s:Subscription

Doc from org.reactivestreams.Subscriber.onSubscribe.

the Subscription that allows requesting data via Subscription#request(long)
