When obtaining a KFunction via a function reference, how do you resolve an "overload resolution ambiguity"?
I am trying to get a KFunction<String> for ResultSet::getString, but there are two versions of that (getString(Int) and getString(String)). How do I tell the compiler I want the Int version?

Provide an expected type in some form, for example:

class A {
    fun getResult(s: String) {}
    fun getResult(i: Int) {}
}

val a: (A, String) -> Unit = A::getResult

[diesieben07]

Yes, but then I have (A, String) -> Unit, which is not assignable to KFunction.

[udalov]

Right. You can also do

val a: kotlin.reflect.KFunction2<A, String, Unit> = A::getResult

[udalov]

KFunction2 is a synthetic type which extends from KFunction and `Function2`; erased to KFunction on JVM

Thank you very much!
