I\'m looking to pass a Class as a parameter to a Scala function like so:

Yes. In general case it's ClassTag/TypeTag - see Mirrors and Reflection

import scala.reflect._
def runtimeClass[T: ClassTag] = classTag[T].runtimeClass

scala> runtimeClass[String]
res2: Class[_] = class java.lang.String

If you really need only to check compile-time (formal) type equality

scala> implicitly[String =:= Double]
:14: error: Cannot prove that String =:= Double.
          implicitly[String =:= Double]
                    ^

If you really need to check only type of object:

 scala> "aa".isInstanceOf[String]
 res4: Boolean = true
