Scala Enumeration Val get value of

Question

In play application I'm using "activate-framework". Enumerations I have to declare this way:

object State extends Enumeration {
case class State(value: Int) extends Val(value)
   val OPEN = State(0)
   val CLOSED = State(1)
}

How can I get State from Int something like:

State.valueOf(1) <==== ??

In model I have a field state:

import model.State.State
case class Task(var name:String, var state:State)

it is State.State case class, how Can I convert Int to State.State class? When I do State(1) I receive State.Value not State.State class.

But when I'm trying to assign to field var state:State.State = State(1) I receive: "error: type mismatch; found : State.Value required: State.State" — Michał Jurczuk, Mar 10 '14 at 16:05

I'm trying to something like this: var state:State.State = State(1), because in model I have a class (State.State) not object (State) – Michał Jurczuk Mar 10 '14 at 15:39

To be able to get value by name you have to declare enum using string constructor:

case class State(value: String) extends Val(value)
