@Carlton Whitehead I didn't quite get what you wanted to do with method references / EventBus. Can you give me an example?

[Carlton Whitehead]

init {
subscribe(this::onEvent)
}

fun onEvent(event: MyEvent) {
// a bit too complex body to leave in the init
// easier entry point for unit testing
}

[edvin]

@Carlton Whitehead subscribe<MyEvent> { onEvent(it) }

[Carlton Whitehead]

That'll do, thanks!

[edvin]

The reason you can't pass it as a function reference is that the function parameter operates on an EventContext. You're losing access to that context by doing this.

[edvin]

So if you need the context, you can pass that as well.

[edvin]

subscribe<MyEvent> { onEvent(this, it) }

[edvin]

That would imply fun onEvent(context: EventContext, event: MyEvent) {}

[edvin]

Function references cannot describe this function call, so you have to call the function explicity.

[Carlton Whitehead]

Ahh, I figured I must be missing something important there

[Carlton Whitehead]

Thanks

[edvin]

Hehe 🙂 Yeah, the function signature gives it away. Function references only work with a single parameter.

[edvin]

You're welcome 🙂
