How to get a `Class[T]`

classTag.scala

import scala.reflect._

class ClassTagOps[T](val t: ClassTag[T]) extends AnyVal {
  def strongRuntimeClass = t.runtimeClass.asInstanceOf[Class[T]]
}

trait ClassTagSyntax {
  def classTagOps[T](t: ClassTag[T]): ClassTagOps[T] = new ClassTagOps[T](t)
}

// Afterward you can:
// import ClassUtils.syntax._
// implicitly[ClassTag[String]].strongRuntimeClass

ClassUtils.scala

// Credit to aluizdinizsilva
object ClassUtils {
  def tagToClass[C](tag: WeakTypeTag[C]) = Class.forName(tag.tpe.baseClasses.head.asClass.fullName).asInstanceOf[Class[C]]
  object syntax extends ClassTagSyntax
}
