Remarks

A connection is used to support perform prompting in a DataTransformation before returning the DataRowReader.

A creator of a transformation typically does not need to explicitly implement this class but can instead use the factory methods CreateConnection(DataTransformationConnectionTransformationExecutor) or CreateConnection(DataTransformationConnectionTransformationExecutor, IEnumerableObject).
