@felixcheung I have an idea of creating an Enum object in scala, like the
example below:
object WeekDay {
sealed trait EnumVal
case object Mon extends EnumVal
case object Tue extends EnumVal
case object Wed extends EnumVal
case object Thu extends EnumVal
case object Fri extends EnumVal
val daysOfWeek = Seq(Mon, Tue, Wed, Thu, Fri)
}
I create a private API of setting the Enum value to a private variable and
a public API of checking the shell type by returning Option[Shell_type]. If
return value is NULL, it is not a shell otherwise, it returns the correct shell
type.
How do you think about this approach?
Thanks!
