Scala学习：枚举类型

枚举

 object Color extends Enumeration {
 val GREEN, RED, YELLOW = Value
 }
 for (color <- Color.values) {
 println(color)
 }

自定义Value

object Direction extends Enumeration{
 val NORTH = Value("N")
 val EAST = Value("E")
 val SOUTH = Value("S")
 val WEST = Value("W")
 }
 for (d <- Direction.values){
 println(d)
 }
