Convert Nested Case Classes to Nested Maps in Scala

Question

I have two nested case classes:

case class InnerClass(param1: String, param2: String)
case class OuterClass(myInt: Int, myInner: InnerClass)
val x = OuterCla         


        

Answer 1

Just call it recursively. So

def getCCParams(cc: AnyRef) =
  (Map[String, Any]() /: cc.getClass.getDeclaredFields) {(a, f) =>
    f.setAccessible(true)
    val value = f.get(cc) match {
      // this covers tuples as well as case classes, so there may be a more specific way
      case caseClassInstance: Product => getCCParams(caseClassInstance)
      case x => x
    }
    a + (f.getName -> value)
  }
