playframework - Scala Enumeration Val get value of -

in play application i'm using "activate-framework". enumerations have declare way:

object state extends enumeration { case class state(value: int) extends val(value)    val open = state(0)    val closed = state(1) }

how can state int like:

state.valueof(1) <==== ??

in model have field state:

import model.state.state case class task(var name:string, var state:state)

it state.state case class, how can convert int state.state class? when state(1) receive state.value not state.state class.

scala> state(1) res0: state.value = closed

And
