virtual DtDatumParam DtDatumRecordSet::datumId	(	DtDatumRecordType	fixedOrVar,
		int	index
	)		const [virtual]

Returns the datum param found in the index'th fixed or variable datum record, depending on whether fixedOrVar is DtFixed or DtVar.

Index is between 1 and numRecords. Returns DtDatumParam(0) if index is out of bounds.

virtual int DtDatumRecordSet::datumSizeBits	(	DtDatumRecordType	fixedOrVar,
		int	index
	)		const [virtual]

Returns the number of bits of data contained in the value fields of the index'th fixed or variable datum record, depending on whether fixedOrVar is DtFixed or DtVar.

If DtFixed, the answer is always 32.

virtual int DtDatumRecordSet::datumSizeBytes	(	DtDatumRecordType	fixedOrVar,
		int	index
	)		const [virtual]

Returns the number of bytes of data contained in the value fields of the index'th fixed or variable datum record, depending on whether fixedOrVar is DtFixed or DtVar.

virtual DtFloat32 DtDatumRecordSet::datumValFloat32	(	DtDatumRecordType	fixedOrVar,
		int	index,
		DtDatumRetCode *	retcode = NULL
	)		const [virtual]

******* INSPECTING DATUM VALUES BY INDEX ********* If you know the data type of the value contained in a particular record, use one of the following to return it.

fixedOrVar (either DtFixed or DtVar) and index (between 1 and numRecords) indicate which record you are inspecting. datumValBytesArray is used when the data type is a character string, or something other than a long, unsigned long, float or double. It returns a pointer to a character string containing the exact bytes in the network representation that represents the value being inspected. The supplied retcode pointer will be filled with DtDatumValid if the value was successfully inspected, and DtDatumBadLength if either the index was invalid, or the size of the data indicated that it could not be interpreted as the chosen data type.

virtual DtFloat32 DtDatumRecordSet::datumValFloat32	(	DtDatumParam	param,
		DtDatumRetCode *	retcode = NULL
	)		const [virtual]

******* INSPECTING DATUM VALUES BY PARAM ID ********* If you know the data type of the value contained in a particular record, use one of the following to return it.

The particular record inspected will be the first one containing param as the datum ID. datumValByteArray is used when the data type is a character string, or something other than a long, unsigned long, float or double. It returns a pointer to a character string containing the exact bytes in the network representation that represents the value being inspected. The supplied retcode pointer will be filled with DtDatumValid if the value was successfully inspected, and DtDatumBadLength if either param was not found, or the size of the data indicated that it could not be interpreted as the chosen data type.

virtual DtDatumParam DtDatumRecordSet::fixedDatumId

(

int

index

)

const [virtual]

Returns the datum param found in the index'th fixed datum record.

Index is between 1 and numRecords. Returns DtDatumParam(0) if index is out of bounds.

virtual void DtDatumRecordSet::getIndex	(	DtDatumParam	param,
		DtDatumRecordType *	fixedOrVar,
		int *	index,
		DtDatumRetCode *	retcode = NULL
	)		const [virtual]

Looks through all fixed and variable records for one containing param as the parameter ID.

If it finds one, fills supplied fixedOrVar pointer with DtFixed or DtVar, and index with the index to indicate which record was found, and fills retcode with DtDatumValid. If param was not found, retcode is filled with DtDatumBadId, and index and fixedOrVar are invalid.

virtual void DtDatumRecordSet::init	(	const DtDatumParam *	fixedParams,
		const DtVarDatumSpec *	specList
	)		[virtual]

****************** MUTATOR FUNCTIONS ******************

Initialize to reflect the fixed parameters and variable parameters and sizes indicated. fixedParams is a NULL- terminated array of DtDatumParams. specList is an array of DtVarDatumSpecs terminated with the DtNullVarDatumSpec constant. This call can be made instead of calls to setNumVarDatumRecords, setNumFixedDatumRecord, and repeated calls to setDatumParam and setVarDataBytes.

******* SETTING DATA VALUES BY INDEX ********* Use one of the following to set the data value in a fixed or variable datum record, depending on the data type of your data.

fixedOrVar (either DtFixed or DtVar) and index (between 1 and numRecords) indicate which record you are modifying. setDatumValBytesArray is used when the data type is a character string, or something other than a long, unsigned long, float or double. It takes a pointer to a character string containing the exact bytes that should be used in the network representation. The supplied retcode pointer will be filled with DtDatumValid if the value was successfully set, DtDatumBadIndex if the index is invalid, and DtDatumBadLength if the size of the data indicated that it could not be set from as the chosen data type.
