Get companion object of class by given generic type Scala

Question

What I am trying to do is to make a function that would take a generic class and use a static method in it (sorry for Java language, I mean method of its companion object).<

Answer 1

Based on the answer by Miquel, here's a method that gets the type reference of the companion object of the specified class object:

  /**
    * Returns the companion object type reference for the specified class
    *
    * @param clazz The class whose companion is required
    * @tparam CT Type of the companion object
    * @return The type of the relevant companion object
    */
  def companionOf[CT](clazz: Class[_]): CT = {
    import scala.reflect.runtime.{currentMirror => cm}
    Try[CT] {
      val companionModule = cm.classSymbol(clazz).companion.asModule
      cm.reflectModule(companionModule).instance.asInstanceOf[CT]
    }.getOrElse(throw new RuntimeException(s"Could not get companion object for $clazz"))
  }
