Is there a way to pass the right hand side of {SomeObject} is {SomeClass} as a parameter? I am trying to perform type checking inside a function where the type to check for meeds to be passed as an argument. Any way to achieve this?

You can pass someClass: KClass<*> and use it someClass.isInstance({SomeObject})

[Ashu]

That syntax doesn't seem right. And I have already tried with KClass but the parameter is not usable as RHS of is keyword.

[ephemient]

if you want to use a "variable" RHS to is, it must be a reified type parameter to an inline function

[ephemient]

https://kotlinlang.org/docs/inline-functions.html#reified-type-parameters

[ephemient]

but for most purposes, I recommend that you write a function taking fun f(t: KClass<T>) and leave inline fun <reified T: Any> f() = f(T::class) as a convenience wrapper only

[ephemient]

yes, isInstance is different syntax than is, but inline should be used judiciously to avoid excessive duplication of bytecode

[Ashu]

I am just trying to improve readability by shifting the type check behind an appropriately named function. The inline function will only have type check and function invocation if it fails.

[Ashu]

Do you think it is worth it?

[ephemient]

sure, just my recommendation and that sounds fine
