trait Rep[T]

Common base trait for all lifted values, including columns.

Common base trait for all lifted values, including columns.

All column operations are added with extension methods that depend on the type inside the Rep. These are defined in:

A Rep[T : TypedType] is always Typed, so that the TypedType can be retrieved directly from the Rep value.
