如何通过将特征与反射混合来访问对象内的对象?

我怎样才能得到一个有反射的物体内的所有物体?

请考虑以下代码:

object MonthDay extends MyEnum {
  //Some important holidays
  object NewYear       extends MonthDay( 1,  1)
  object UnityDay      extends MonthDay(11,  9)
  object SaintNicholas extends MonthDay(12,  6)
  object Christmas     extends MonthDay(12, 24)
}

class MonthDay(month: Int, day: Int)

trait MyEnum {
  val values: List[MonthDay] = this.getClass.getField("MODULE$")...
  val next: MonthDay = ...
  val previous: MonthDay = ...
}

//Of course the user can create his own MonthDays
val myBirthDay = new MonthDay(month, day)

if(!MonthDay.values.contains(myBirthDay)) "Well, I probably have to work"
else "Great, it is a holiday!"

我想有个特点( MyEnum )我可以将其混合到包含“枚举对象”的对象中,并使用方法返回它们的列表( def values: List[MonthDay] )或者迭代它们( def next: MonthDay 或 def previous: MonthDay ) 不重复几次 (这绝对至关重要!).

我的想法是 values 访问 MonthDay 对象并查找它们正在扩展的类的所有单例对象( 月日 )带着沉思。
