Get Mono or Flux object type during runtime

Question

I have Flux or Mono which is being populated with different custom objects which i am not aware of.

I want to retrieve Object class name without blocking the Flux or Mono.

Answer 1

You can do this by mapping Mono like such:

Mono<String> mono = Mono.just(...some object goes here)
    .map(object -> object.getClass().getSimpleName());

It should be relatively obvious what is going on here -- we are mapping the object to the object's class name (all while staying inside mono )

Flux<String> mono = Flux.fromIterable(...some list of objects)
    .flatMap(object -> object.getClass().getSimpleName);

(Note: I'm not super sure about Flux ... writing this code without an IDE. But it should be very close.)
