Class Inheritance
All Implemented Interfaces
reactor.core.publisher.SourceProducer, org.reactivestreams.Publisher, reactor.core.Scannable, reactor.core.Fuseable, reactor.core.Fuseable.ScalarCallable, java.util.concurrent.Callable
Imports
java.util.Objects, reactor.core.CoreSubscriber, .Fuseable
A Stream that emits only one value and then complete.

Since the flux retains the value in a final field, any this#subscribe(Subscriber) will replay the value. This is a "Cold" fluxion.

Create such flux with the provided factory, E.g.: 

Flux.just(1).subscribe(
   log::info,
   log::error,
   ()-> log.info("complete")
)
Will log: 
1
complete

scanUnsafeback to summary
public Object scanUnsafe(Scannable.Attr<T> key)

Overrides default reactor.core.publisher.SourceProducer.scanUnsafe.

Doc from reactor.core.Scannable.scanUnsafe.

This method is used internally by components to define their key-value mappings in a single place. Although it is ignoring the generic type of the Attr key, implementors should take care to return values of the correct type, and return null if no specific value is available.

For public consumption of attributes, prefer using scan(Attr), which will return a typed value and fall back to the key's default if the component didn't define any mapping.

Parameters
key:Scannable.Attr<T>

a Attr to resolve for the component.

Returns:Object

the value associated to the key for that specific component, or null if none.

subscribeback to summary
public void subscribe(final CoreSubscriber<? super T> actual)

Implements abstract reactor.core.publisher.Flux.subscribe.

Implements reactor.core.CorePublisher.subscribe.

Doc from reactor.core.publisher.Flux.subscribe.

An internal Publisher#subscribe(Subscriber) that will bypass Hooks#onLastOperator(Function) pointcut.

In addition to behave as expected by Publisher#subscribe(Subscriber) in a controlled manner, it supports direct subscribe-time Context passing.

Parameters
actual:CoreSubscriber<? super T>

the Subscriber interested into the published sequence
