Instantiating a case class from a list of parameters

Question

Given:

case class Foo(a: Int, b: String, c: Double)

you can say:

val params = Foo(1, \"bar\", 3.14).productIterator.toList
         


        

Answer 1

You could use pattern matching like:

params match {                                   
 case List(x:Int, y:String, d:Double) => Foo(x,y,d)
}
