NullSink

object NullSink extends Source with BaseNullSource with typed.TypedSink[Any]

This can be used to cause cascading to run a flow, but discard the output. The only place this is likely of use is to do some (non-recommended, but sometimes the most expediant way to accomplish some task).

  28. def transformInTest: Boolean

    The mock passed in to scalding.

    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.
