Method Details

subscribeActual

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

Description copied from class: Single

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 Single.subscribe(SingleObserver) before this method gets called.

Specified by:

subscribeActual in class Single<R>

Parameters:

observer - the SingleObserver to handle, not null
