Example of Mono<Void>

[Léonard Schneider]

Hi,

I want to implement a Mono that returns nothing, but evaluates asynchronously a side effect function. The only ways to create a Mono<Void> in the API I see are justOrEmpty, which evaluates the arg given or empty that does nothing. I was expecting a Mono.fromConsumer, but there is only a Mono.fromSupplier, which can't be used for Void.

Or should I do (which seems too late): Mono.empty().doOnSuccess(() -> System.println("Hello")) ?

Am I missing something?

Thanks for your help.

BR,

Leo

I think I've got it.

Mono.create(s -> {
  System.println("Hello");

  s.success();
});
