Modifier and Type	Method and Description
protected void	subscribeActual(Observer<? super T> the incoming Observer, never null observer) Implements abstract io.reactivex.Observable.subscribeActual. Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming `Observer`s.

protected 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 `Observer`s. 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.

public void onComplete() Overrides io.reactivex.internal.observers.BasicFuseableObserver.onComplete. Implements io.reactivex.Observer.onComplete. Doc from io.reactivex.Observer.onComplete.

requestFusion	back to summary
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`. Annotations @Override

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
