Constructor & Destructor Documentation

FileDataSet() [1/4]

SEGY::FileDataSet::FileDataSet	(	const IOPar &	iop,
		ascistream &
	)

Reads old version of file into memory.

FileDataSet() [2/4]

SEGY::FileDataSet::FileDataSet

(

const IOPar &

iop

)

Creates empty set, can later be filled from scanning.

~FileDataSet()

SEGY::FileDataSet::~FileDataSet

(

)

FileDataSet() [3/4]

SEGY::FileDataSet::FileDataSet	(	const IOPar &	,
		const char *	filename,
		od_stream_Pos	start,
		const DataCharacteristics &	int32
	)

Reads new version of file, only auxdata is read in, the bulk of the data remains on disk.

FileDataSet() [4/4]

SEGY::FileDataSet::FileDataSet

(

const FileDataSet &

fd

)

Not implemented, just to make linker complain.
