public void clear()

Overrides io.reactivex.rxjava3.internal.observers.BasicFuseableObserver.clear.

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

Removes all enqueued items from this queue.

Implements io.reactivex.rxjava3.core.Observer.onComplete.

Notifies the Observer that the Observable has finished sending push-based notifications.

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

public void onNext(T value)

Implements io.reactivex.rxjava3.core.Observer.onNext.

Doc from io.reactivex.rxjava3.core.Observer.onNext.

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either onComplete or onError.

Parameters
value:T

the item emitted by the Observable

pollback to summary
public T 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:T

the item or null to indicate an empty queue

Annotations

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