How is `toString` in `scala.Enumeration$Value` implemented?
- by Red Hyena
I have an enum Fruit defined as:
object Fruit extends Enumeration {
val Apple, Banana, Cherry = Value
}
Now printing values of this enum, on Scala 2.7.x gives:
scala> Fruit foreach println
line1$object$$iw$$iw$Fruit(0)
line1$object$$iw$$iw$Fruit(1)
line1$object$$iw$$iw$Fruit(2)
However the same operation on Scala 2.8 gives:
scala> Fruit foreach println
warning: there were deprecation warnings; re-run with -deprecation for details
Apple
Banana
Cherry
My question is:
How is the method toString in Enumeration in Scala 2.8 is implemented? I tried looking into the source of Enumeration but couldn't understand anything.
