Detailed Description

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.

size

)

[protected, virtual]

Changes the size of the datumRecSet, by asking my PDU to change size, then reinitializing to use the right piece of the PDU's buffer.

Reimplemented from DtBaseMsg.

virtual void DtPduDatumRecordSet::deleteBytes	(	int	offset,
		int	numBytes
	)		[protected, virtual]

Deletes numBytes bytes at the indicated offset in the net rep, by asking my PDU to insert bytes, then reinitializing to use the right piece of the PDU's buffer.

Reimplemented from DtBaseMsg.

virtual void DtPduDatumRecordSet::deleteBytes	(	void *	addr,
		int	numBytes

Reimplemented from DtBaseMsg.

virtual void DtPduDatumRecordSet::insertBytes	(	int	offset,
		int	numBytes
	)		[protected, virtual]

Inserts numBytes zeroed-out bytes at the indicated offset into the net rep, by asking my PDU to insert bytes, then reinitializing to use the right piece of the PDU's buffer.

Reimplemented from DtBaseMsg.

virtual void DtPduDatumRecordSet::insertBytes	(	void *	addr,
		int	numBytes
	)		[protected, virtual]

Inserts numBytes zeroed-out bytes at the indicated addr within the net rep, by asking my PDU to insert bytes, then reinitializing to use the right piece of the PDU's buffer.
