Given an instance of a class, we can obviously return its name:
trait MixedInClassDiscovery {
val className = this.getClass.getName
}
class AClass extends MixedInClassDiscovery {
...
this.className // returns "AClass"
...
}
But this way uses reflection, once for every instance of AClass
. Can the same be done once for every class, instead?
One solution which comes to mind is to mix it into companion objects instead of classes themselves.
