Method Details

source
Description copied from interface:HasUpstreamMaybeSource
Returns the upstream source of this Maybe.Allows discovering the chain of observables.
- Specified by:
source
in interfaceHasUpstreamMaybeSource<T>
- Returns:
- the source MaybeSource
-
fuseToMaybe
Description copied from interface:FuseToMaybe
Returns a (direct) Maybe for the operator.The implementation should handle the necessary RxJavaPlugins wrapping.
- Specified by:
fuseToMaybe
in interfaceFuseToMaybe<T>
- Returns:
- the Maybe instance
-
subscribeActual
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<Boolean>
- Parameters:
observer
- theSingleObserver
to handle, notnull
