How to pattern match large Scala case classes?

Question

Consider the following Scala case class:

case class WideLoad(a: String, b: Int, c: Float, d: ActorRef, e: Date)

Pattern matching allows me

Answer 1

You can create a new case class which is a summary of your larger case class

case class WideLoad(a: String, b: Int, c: Float, d: ActorRef, e: Date)
case class WideLoadSummary(d: ActorRef, e: Date)

And then pattern match as normal.

val someVal = WideLoadSummary(wideload.d, wideload.e)

someVal match {
    case WideLoadSummary(d, _) => d ! SomeMessage(...)
}
