Method Detail

onSubscribe

public final 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>

request

protected final void request(long n)

Requests from the upstream Subscription.

Parameters:

n - the request amount, positive

cancel

protected final void cancel()

Cancels the upstream's Subscription.

onStart

protected void onStart()

Called once the subscription has been set on this observer; override this to perform initialization or issue an initial request.

The default implementation requests Long.MAX_VALUE.
