Should I prefer sealed class or Enumeration in Scala?

Question

I\'m trying to implement a Plurk API biding for Scala, but I have a design choice to made.

For example, the gender attribute of a Plurk user could be one of \"male\"

Answer 1

Using Enumeration is also quite a bit cheaper in terms of class count. In the Gender example that does not matter, but it might start to matter if you want to model processor instructions by an enumeration with 100+ elements.

Answer 2

If you don't need to iterate over your objects of Gender or need methods like next and previous, classes and objects is the right solution.

If you need the features of the "classes and objects" and of "scala.Enumeration" this and this question could be of interest to you.
