Is there any easy syntax/shortcut to declare a literal Java Class<T?>? E.G. I need a class literal for a Double? , so I was going to use Double::class.javaObjectType, but I have to “unsafely” cast that to make the compiler happy. Simplified example of what I’m doing, sort of: https://pl.kotl.in/OQI60v_tV

hmm
that does seem closer to correct, but I’m still having an issue with a reified type parameter - if T is unbound, it can include nullability at the declaration (what I want), but then T::class.java doesn’t meet the T & Any constraint. If I make the inline fun <reified T: Any>, it then prevents me from returning null from a getValue lambda

I haven't fully understood what you're going for, but have you considered KType instead? Which you can get from typeOf<reified T>(). That's has all the compile time type information that kotlin has, and you can get a KClass from it if needed

[Paul Griffith]

I ultimately need a plain-old-java Class because this is ultimately for a Swing GUI sad panda

You’re right; my fault. That’s basically what I’ve been using this whole time, but now to try to recycle things I’m manually initializing `Column`s instead of using the delegate: https://pl.kotl.in/l4NV1QH3E

That’s where the unchecked cast is necessary

Ah, that got me to something I’m happy with - inline operator fun <R, reified C> invoke() on Column, for a fake-constructor with the benefit of <reified T> - thanks
