trait ScalaReflection extends AnyRef

Support for generating catalyst schemas for scala objects. Note that unlike its companion object, this trait able to work in both the runtime and the compile time (macro) universe.

    Return the Scala Type for T in the current classloader mirror.

    Return the Scala Type for T in the current classloader mirror.

    Use this method instead of the convenience method universe.typeOf, which assumes that all types can be found in the classloader that loaded scala-reflect classes. That's not necessarily the case when running using Eclipse launchers or even Sbt console or test (without fork := true).
