Scala - Enumeration

ScalaでEnumerationを継承してenumを定義する例．

object Weekdays extends Enumeration {
  type WEEKDAY = Value
  val MON, TUE, WED = Value
}

object MyMain {

  def isMonday(w:Weekdays.Value) = {
    w == Weekdays.MON
  }

  def main(args:Array[String]) = {
    val w = Weekdays.MON
    val w2 = Weekdays.WED
    println(isMonday(w))
    println(isMonday(w2))
  }
}
