Reactor Core 3.6.0 · reactor.core.publisher.FluxUsingWhen

Uses a resource that is lazily generated by a Publisher for each individualSubscriber, while streaming the values from a Publisher derived from the same resource. Whenever the resulting sequence terminates, the relevant Function generates a "cleanup" Publisher that is invoked but doesn't change the content of the main sequence. Instead it just defers the termination (unless it errors, in which case the error suppresses the original termination signal).

Note that if the resource supplying Publisher emits more than one resource, the subsequent resources are dropped (Operators#onNextDropped(Object, Context)). If the publisher errors AFTER having emitted one resource, the error is also silently dropped (Operators#onErrorDropped(Throwable, Context)).

public Object	scanUnsafe(Scannable.Attr<T> a `Attr` to resolve for the component. key) Overrides default reactor.core.publisher.SourceProducer.scanUnsafe. This method is used internally by components to define their key-value mappings in a single place.
public void	subscribe(CoreSubscriber<? super T> the `Subscriber` interested into the published sequence actual) Implements abstract reactor.core.publisher.Flux.subscribe. Implements reactor.core.CorePublisher.subscribe. An internal `Publisher#subscribe(Subscriber)` that will bypass `Hooks#onLastOperator(Function)` pointcut.
