Method Details

onSubscribe

public void onSubscribe(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.

Specified by:

onSubscribe in interface FlowableSubscriber<T>

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<T>

onNext

public void onNext(T t)

Specified by:

onNext in interface org.reactivestreams.Subscriber<T>

addInner

boolean addInner(FlowableFlatMap.InnerSubscriber<T,U> inner)

removeInner

void removeInner(FlowableFlatMap.InnerSubscriber<T,U> inner)

getMainQueue

SimpleQueue<U> getMainQueue()

tryEmitScalar

void tryEmitScalar(U value)

tryEmit

Specified by:
