In Kotlin. I need a lambda: (T)->Unit `<T: Any`> but allow null when T is nullable type... How to do that? Thank you

[Shawn]

<T : Any> disallows T from being a nullable type

[Shawn]

maybe you can accept T? instead?

[fatih]

<T : Any?>

[Shawn]

you can just get rid of the type bound since T is allowed to be Any? by default lol

[Shawn]

I’m assuming you can’t just change the bound, otherwise you wouldn’t have this problem

[Casey Brooks]

If you do <T>, it should be able to accept both nullable and non-null types. The type of (T)->Unit should then be the same. https://pl.kotl.in/Zo8dB908p

They are suggesting to remove the : Any type bound. This bound prevents T from being nullable, because null is not assignable to Any

[Dico]

The default type bound, if you specify none, is Any?, which null is assignable to.

Thank you for your helps.

I can't change the bound because I need KClass<T> parameter...
