Is this for compatibility with Java?, the same can already be expressed with ADTs in Kotlin:

sealed class MyLongClassNameActivityMode
object WaitingInput : MyLongClassNameActivityMode()
object Loading : MyLongClassNameActivityMode()
object Complete : MyLongClassNameActivityMode()

fun changeUiMode(mode: MyLongClassNameActivityMode) = when (mode) {
  is WaitingInput -> TODO()
  is Loading -> TODO()
  is Complete -> TODO()
}
