What's the deal with

KFunction1<@ParameterName(name = "ctx") RoutingContext, Unit>

? Is it better than

(ctx: RoutingContext) -> Unit

?

The second one I’ve used before, but that forces me to pass in the context as far as I can see.

router.blockingPost2("/blah", LoginController.logout(context))

The first one was generated by IntelliJ when I typed

HomeController::default

and alt-entered it to autocomplete the signature of the extension function. I’m still reading up on what KFunction1 actually does, looks like reflection + magic.

Their usage must be the same AFAIK
