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.

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

public void onSuccess(T t)

Implements io.reactivex.rxjava3.core.MaybeObserver.onSuccess, io.reactivex.rxjava3.core.SingleObserver.onSuccess.

Doc from io.reactivex.rxjava3.core.MaybeObserver.onSuccess.

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.

The Maybe will not call this method if it calls onError.

Parameters
t:T

the item emitted by the Maybe

Annotations
@Override
pollback to summary
public R poll() throws Throwable

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:R

the item or null to indicate an empty queue

Annotations
@Override
@Nullable
Exceptions
Throwable:
if some pre-processing of the dequeued item (usually through fused functions) throws.
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.
