Okay, considering the two questions I attached to the question, here is what I'd use:
object Implicits {
implicit class CaseClassToString(c: AnyRef) {
def toStringWithFields: String = {
val fields = (Map[String, Any]() /: c.getClass.getDeclaredFields) { (a, f) =>
f.setAccessible(true)
a + (f.getName -> f.get(c))
}
s"${c.getClass.getName}(${fields.mkString(", ")})"
}
}
}
case class PriceMove(price: Double, delta: Double)
object Test extends App {
import Implicits._
println(PriceMove(1.23, 2.56).toStringWithFields)
}
This produces:
PriceMove(price -> 1.23, delta -> 2.56)
