hello, is it possible to wrap on a sealed class classes of external libs?

[gildor]

wrap on?

[orestisfou]

so let's say I use a lib that has classes A and B. Now I want to create a sealed class that contains those two classes. Is this possible and if yes what is the syntax?

For example if a lib contains Dog and Cat can I create a sealed class called Animal that wraps those two types?

[gildor]

Yes, sure:

sealed class Animal
data class DogWrapper(val dog: Dog) : Animal()
data class CatWrapper(val cat: Cat) : Animal()

[orestisfou]

thanks

[gildor]

also it can be something like:

sealed class Animal<T> {
    abstract val value: T
}
data class DogWrapper(override val value: Dog) : Animal<Dog>()
data class CatWrapper(override val value: Cat) : Animal<Cat>()

[gildor]

No big difference, but at least you can get value, but only as Any

[orestisfou]

cool, thank you
