A modern programming language that makes developers happier.

kotlinlang

is there a way other than going down with annotation and code generation?

Had similar problem. You could make all the companion objects implement a common interface or base class. Then declare the extension function on the interface.

but the problem is referring to `names` from the extension function

The interface will declare a `val names: IntBuffer`, which you can then access.

Oh I think I understand now, you want to declare the extension function on the enum entries?

```
interface Whatever { val names: IntBuffer }
enum class Buffer : Whatever {
 VERTEX, ELEMENT;
 companion object { val names: IntBuffer }
override val names: IntBuffer get() = Companion.names
}
inline fun Whatever.bind(..) {
   // do something on names
}
```
