TypedDelimited

trait TypedDelimited[T] extends SchemedSource with DelimitedScheme with Mappable[T] with TypedSink[T]

Allows you to set the types, prefer this: If T is a subclass of Product, we assume it is a tuple. If it is not, wrap T in a Tuple1: e.g. TypedTsv[Tuple1[List[Int]]]

    The mock passed in to scalding.JobTest may be considered as a mock of the Tap or the Source. By default, as of 0.9.0, it is considered as a Mock of the Source. If you set this to true, the mock in TestMode will be considered to be a mock of the Tap (which must be transformed) and not the Source.
