I am getting an expected overload resolution ambiguity issue when I do a function reference on an overloaded Java method (again, as expected). For my use case (adding an extension method on KFunction) I can’t really do a forwarding lambda and I was hoping to avoid a local var just to help the compiler out.
Are there any plans or issues I can watch for compile-time type ascription inside an expression as opposed to on assignment?
Also, how do I turn a function reference to a KFunction so I can invoke my extension method? For example, say I have the following extension function:
val <R> KFunction<R>.declarer: Class<*> get() = this.javaMethod!!.declaringClass
Now I want to get that for
ByteBuffer.put(ByteArray!, Int, Int): ByteBuffer. How would I do this? I see the
reflect method but that doesn’t feel right, but it looks like this:
val temp: ByteBuffer.(ByteArray, Int, Int) -> ByteBuffer = ByteBuffer::put val temp2 = temp.reflect()?.declarer
Obviously this is just an example to demonstrate my problem. Any suggestions?
I got a way to make the type I want without a local var I suppose:
inline fun <T> forceType(fn: T) = fn val fn = forceType<ByteBuffer.(ByteArray, Int, Int) -> ByteBuffer>(ByteBuffer::put)
I still don’t know how to get a safe
KFunction out of that like I easily could if it weren’t an overload I was referencing. Help appreciated.
