subscribeActual
protected void subscribeActual(SingleObserver<? super T> observer)
Description copied from class:Single
Implement this method in subclasses to handle the incomingSingleObserver
s.There is no need to call any of the plugin hooks on the current
Single
instance or theSingleObserver
; all hooks and basic safeguards have been applied bySingle.subscribe(SingleObserver)
before this method gets called.- Specified by:
subscribeActual
in classSingle<T>
- Parameters:
observer
- theSingleObserver
