Scala: How can I get the class name of a variable in a function?

I would like to do something like def foo[V] : String = { V.getName }

, but of course it is not correct. I am using the name of the class name to locate the file containing the serialized instance of the class on the file system.

def className[V](implicit ev: ClassTag[V]) : String = ev.runtimeClass.getName()

Using



className[String]

gives java.lang.String

className[Map[String,String]]

gives scala.collection.immutable.Map
