Scala case classes with Mixin traits
I am trying to use a trait as a mixin with a case class.
case class Team(name:String)
trait WinStreak{}
and I would like to use it like so:
val team = Team("name") with WinStreak
Apparently I cannot do this开发者_开发问答. Is this because case classes use the companion object to create an instance of your class? I know the other solution would be to just extend the trait in my class def, but I would like to know if its possible to create it mixin style.
Because Team("name")
is actually a method call to Team.apply("name")
, which create the object inside the apply method.
Create the object using new
keyword should do the trick:
case class Team(name:String)
trait WinStreak{}
val x = new Team("name") with WinStreak
