class ExampleEvent : Event
val bus = EventBus()
bus.register<ExampleEvent> { event ->
 println("Received event")
}
bus.post(ExampleEvent())

Or using annotations:

class Listener {
 @Subscribe
 fun handle(event: ExampleEvent) {
 println("Event received")
 }
}
val bus = EventBus()
bus.register(Listener())
bus.post(ExampleEvent())
