Consider something like this:

object Singleton

val cls: Class[Singleton] = ???

What do I have to write instead of ????

I tried classOf[Singleton], classOf[Singleton.type], Singleton.type, but nothing worked.

(I know of course about getClass, the runtime version of classOf, but that’s not what I’m asking.)

    Here a solution, but it’s not pretty …

    object Singleton

val cls : Class[Singleton] = Singleton.getClass.asInstanceOf[Class[Singleton]]

    Edit: completed the solution after reading another question/answer: Scala equivalent of Java java.lang.Class<T> Object

    Note1: type erasure would prevent this from being particularly useful, e.g. in pattern matching. See referenced question/answer, above, for a good explanation

    Note2: the scala -explaintypes flag is quite handy in understanding type errors.
