trait TypeDescriptor[T] extends Serializable

This class is used to bind together a Fields instance which may contain a type array via getTypes, a TupleConverter and TupleSetter, which are inverses of one another. Note the size of the Fields object and the arity values for the converter and setter are all the same. Note in the com.twitter.scalding.macros package there are macros to generate this for case classes, which may be very convenient.
