MaybeFromSingle

public MaybeFromSingle(SingleSource<T> source)

Method Details

source

public SingleSource<T> source()

Description copied from interface: HasUpstreamSingleSource

Returns the upstream source of this Single.

Allows discovering the chain of observables.

Specified by:

source in interface HasUpstreamSingleSource<T>

Returns:

the source SingleSource

subscribeActual

protected void subscribeActual(MaybeObserver<? super T> observer)

Description copied from class: Maybe

Implement this method in subclasses to handle the incoming MaybeObservers.

There is no need to call any of the plugin hooks on the current Maybe instance or the MaybeObserver; all hooks and basic safeguards have been applied by Maybe.subscribe(MaybeObserver) before this method gets called.

Specified by:

subscribeActual in class Maybe<T>

Parameters:

observer - the MaybeObserver to handle, not null
