Method Detail

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 value)

Specified by:

onNext in interface org.reactivestreams.Subscriber<T>

onError

public void onError(java.lang.Throwable e)

Specified by:

onError in interface org.reactivestreams.Subscriber<T>

onComplete

public void onComplete()

Specified by:

onComplete in interface org.reactivestreams.Subscriber<T>

cancel

public void cancel()

Specified by:

cancel in interface org.reactivestreams.Subscription

request

public void request(long n)

Specified by:

request in interface org.reactivestreams.Subscription

poll

@Nullable
public T poll()

Description copied from interface: SimpleQueue

Tries to dequeue a value (non-null) or returns null if the queue is empty.

If the producer uses SimpleQueue.offer(Object, Object) and when polling in pairs, if the first poll() returns a non-null item, the second poll() is guaranteed to return a non-null item as well.

Specified by:

poll in interface SimpleQueue<T>

Returns:

the item or null to indicate an empty queue

isEmpty

public boolean isEmpty()

Description copied from interface: SimpleQueue

Returns true if the queue is empty.

Note however that due to potential fused functions in SimpleQueue.poll() it is possible this method returns false but then poll() returns null because the fused function swallowed the available item(s).

Specified by:

isEmpty in interface SimpleQueue<T>

Returns:

true if the queue is empty

clear

public void clear()

Description copied from interface: SimpleQueue

Removes all enqueued items from this queue.

Specified by:

clear in interface SimpleQueue<T>

requestFusion

public int requestFusion(int mode)

Description copied from interface: QueueFuseable

Request a fusion mode from the upstream.

This should be called before onSubscribe returns.

Calling this method multiple times or after onSubscribe finished is not allowed and may result in undefined behavior.

Specified by:

requestFusion in interface QueueFuseable<T>

Parameters:

mode - the requested fusion mode, allowed values are QueueFuseable.SYNC, QueueFuseable.ASYNC, QueueFuseable.ANY combined with QueueFuseable.BOUNDARY (e.g., requestFusion(SYNC | BOUNDARY)).

Returns:

the established fusion mode: QueueFuseable.NONE, QueueFuseable.SYNC, QueueFuseable.ASYNC.

innerComplete

void innerComplete(FlowableFlatMapCompletable.FlatMapCompletableMainSubscriber.InnerConsumer inner)

innerError

void innerError(FlowableFlatMapCompletable.FlatMapCompletableMainSubscriber.InnerConsumer inner,
                java.lang.Throwable e)
