public void subscribeActual(Observer<? super T> observer)

Implements abstract io.reactivex.Observable.subscribeActual.

Doc from io.reactivex.Observable.subscribeActual.

Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Observers.

There is no need to call any of the plugin hooks on the current Observable instance or the Observer; all hooks and basic safeguards have been applied by subscribe(Observer) before this method gets called.

Parameters
observer:Observer<? super T>

the incoming Observer, never null

public boolean isEmpty()

Implements io.reactivex.internal.fuseable.SimpleQueue.isEmpty.

Doc from io.reactivex.internal.fuseable.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 T poll()

Implements io.reactivex.internal.fuseable.SimpleQueue.poll.

Doc from io.reactivex.internal.fuseable.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

public int requestFusion(int mode)

Implements io.reactivex.internal.fuseable.QueueFuseable.requestFusion.

Doc from io.reactivex.internal.fuseable.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.
