subscribeActual
protected void subscribeActual(MaybeObserver<? super T> observer)
Description copied from class:Maybe
Implement this method in subclasses to handle the incomingMaybeObserver
s.There is no need to call any of the plugin hooks on the current
Maybe
instance or theMaybeObserver
; all hooks and basic safeguards have been applied byMaybe.subscribe(MaybeObserver)
before this method gets called.- Specified by:
subscribeActual
in classMaybe<T>
- Parameters:
observer
- theMaybeObserver
to handle, notnull
