Package io.reactivex.rxjava3.internal.operators.maybe

Class MaybeToSingle<T>

java.lang.Object

io.reactivex.rxjava3.core.Single<T>

io.reactivex.rxjava3.internal.operators.maybe.MaybeToSingle<T>

Type Parameters:

T - the value type

All Implemented Interfaces:

SingleSource<T>, HasUpstreamMaybeSource<T>

public final class MaybeToSingle<T>
extends Single<T>
implements HasUpstreamMaybeSource<T>

Wraps a MaybeSource and exposes its onSuccess and onError signals and signals NoSuchElementException for onComplete if defaultValue is null.

Method Detail

source

public MaybeSource<T> source()

Description copied from interface: HasUpstreamMaybeSource

Returns the upstream source of this Maybe.

Allows discovering the chain of observables.

Specified by:

source in interface HasUpstreamMaybeSource<T>

Returns:

the source MaybeSource

subscribeActual

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

Description copied from class: Single

Implement this method in subclasses to handle the incoming SingleObservers.

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

Specified by:

subscribeActual in class Single<T>

Parameters:

observer - the SingleObserver to handle, not null
