Method Detail

public void cancel()

Implements org.reactivestreams.Subscription.cancel.

Doc from org.reactivestreams.Subscription.cancel.

Request the Publisher to stop sending data and clean up resources.

Data may still be sent to meet previously signalled demand after calling cancel.

public void onComplete()

Doc from org.reactivestreams.Subscriber.onComplete.

Successful terminal state.

No further events will be sent even if Subscription#request(long) is invoked again.

public void onError(Throwable t)

Implements org.reactivestreams.Subscriber.onError.

Doc from org.reactivestreams.Subscriber.onError.

Failed terminal state.

No further events will be sent even if Subscription#request(long) is invoked again.

Parameters
t:Throwable

the throwable signaled

Annotations

public void onNext(T t)

Implements org.reactivestreams.Subscriber.onNext.

Doc from org.reactivestreams.Subscriber.onNext.

Data notification sent by the Publisher in response to requests to Subscription#request(long).

Parameters
t:T

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)

public void request(long n)

Implements org.reactivestreams.Subscription.request.

Doc from org.reactivestreams.Subscription.request.

No events will be sent by a Publisher until demand is signaled via this method.

It can be called however often and whenever needed—but if the outstanding cumulative demand ever becomes Long.MAX_VALUE or more, it may be treated by the Publisher as "effectively unbounded".

Whatever has been requested can be sent by the Publisher so only signal demand for what can be safely handled.

A Publisher can send less than is requested if the stream ends but then must emit either Subscriber#onError(Throwable) or Subscriber#onComplete().

Parameters
n:long

the strictly positive number of elements to requests to the upstream Publisher
