Answer is probably no but is there a way to either
• reset a lateinit property back to null?
• do it myself with a getter that returns non-null with !! and a setter that accepts null?

[Ruckus]

You could do that pretty simple with a delegate

[karelpeeters]

Really? If you can't even do it by manually writing getter and setter how would a delegate do it?

[karelpeeters]

Unlesss you mean actually keeping the delegate object around and calling a reset() function on that, but that's super awkward.

[louiscad]

@karelpeeters Have a nullable var, and an inline val that gets the var with !!

[Ruckus]

Yeah, I guess I didn't think that through all the way

[karelpeeters]

@louiscad I'll have to resort to something like that, still annoying.

[karelpeeters]

@Ruckus Haha that was my first reaction too: "I'll just write a delegate for it".

[louiscad]

@karelpeeters You can also declare a .toPlatformType() extension function that returns the inferred type from a generic static java method. It doesn't work outside Kotlin/JVM though.

[karelpeeters]

public class JavaClass {
    public static <T> T platform() {
        return null;
    }
}

public class KotlinTest {
    val x = JavaClass.platform<Int>()
}

makes x: Int!. Damm that is evil.
