Method Detail

cancelback to summary
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.

clearback to summary
public void clear()

Implements io.reactivex.rxjava3.operators.SimpleQueue.clear.

Doc from io.reactivex.rxjava3.operators.SimpleQueue.clear.

Removes all enqueued items from this queue.

isEmptyback to summary
public boolean isEmpty()

Implements io.reactivex.rxjava3.operators.SimpleQueue.isEmpty.

Doc from io.reactivex.rxjava3.operators.SimpleQueue.isEmpty.

Returns true if the queue is empty.

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

Returns:boolean

true if the queue is empty

Annotations
@Override
onCompleteback to summary
public void onComplete()

Implements org.reactivestreams.Subscriber.onComplete.

Doc from org.reactivestreams.Subscriber.onComplete.

Successful terminal state.

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

Annotations
@Override
onErrorback to summary
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
@Override
onNextback to summary
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 org.reactivestreams.Subscriber.onSubscribe.

Doc from org.reactivestreams.Subscriber.onSubscribe.

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

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

Annotations
@Override
pollback to summary
public T poll()

Implements io.reactivex.rxjava3.operators.SimpleQueue.poll.

Doc from io.reactivex.rxjava3.operators.SimpleQueue.poll.

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

If the producer uses 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.

Returns:T

the item or null to indicate an empty queue

Annotations
@Nullable
@Override
requestback to summary
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

Annotations
@Override
requestFusionback to summary
public int requestFusion(int mode)

Implements io.reactivex.rxjava3.operators.QueueFuseable.requestFusion.

Doc from io.reactivex.rxjava3.operators.QueueFuseable.requestFusion.

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.

Parameters
mode:int

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

Returns:int

the established fusion mode: NONE, SYNC, ASYNC.
