Method Detail
-
source
public org.reactivestreams.Publisher<T> source()
Description copied from interface:HasUpstreamPublisher
Returns the source Publisher.This method is intended to discover the assembly graph of sequences.
- Specified by:
source
in interfaceHasUpstreamPublisher<T>
- Returns:
- the source Publisher
-
fuseToFlowable
public Flowable<T> fuseToFlowable()
Description copied from interface:FuseToFlowable
Returns a (direct) Flowable for the operator.The implementation should handle the necessary RxJavaPlugins wrapping.
- Specified by:
fuseToFlowable
in interfaceFuseToFlowable<T>
- Returns:
- the Flowable instance
-
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
