How to get constructor arguments in a method using typetags/mirrors?

Question

For Case Class:

case class MyClass(param1: String, param2: String)

Why does this reflective method:

import scala.reflect.ru         


        

Answer 1

getSettings(MyClass)

MyClass is the companion object of class MyClass. It has no constructor parameters.

You should rewrite your code like this:

def getSettings[T]()(implicit tag: TypeTag[T]) {
  ...
}

scala> getSettings[MyClass]
List((param1,String), (param2,String))
