An instance of this class is a DtDatumRecordSet that uses a part of a DtPduWithData as its network representation.
Normally, a DtDatumRecord manages the memory associated with its network representation through its DtBaseMsg base class. However, since a DtPduWithData's netRep memory is managed by that DtPduWithData, DtPduDatumRecordSets must defer ITS memory management responsibilities to the DtPduWithData. This is accomplished by overriding changeSize, addBytes and deleteBytes here, with versions that call the DtPduWithData's versions of the functions. No one should need to use this class, except for DtPduWithData.
