protected void subscribeActual(SingleObserver<? super R> observer)

Implements abstract io.reactivex.Single.subscribeActual.

Doc from io.reactivex.Single.subscribeActual.

Implement this method in subclasses to handle the incoming SingleObservers.

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

Parameters
observer:SingleObserver<? super R>

the SingleObserver to handle, not null
