Function Documentation

SCIP_RETCODE SCIPreaderCopyInclude	(	SCIP_READER *	reader,
		SCIP_SET *	set
	)

copies the given reader to a new scip

Parameters

reader	reader
set	SCIP_SET of SCIP to copy to

		SCIP_READERDATA *	readerdata
	)

creates a reader

Parameters

reader	pointer to store reader
name	name of reader
desc	description of reader
extension	file extension that reader processes
readerdata	reader data

SCIP_RETCODE SCIPreaderFree	(	SCIP_READER **	reader,
		SCIP_SET *	set
	)

frees memory of reader

Parameters

reader	pointer to reader data structure
set	global SCIP settings

static SCIP_Bool readerIsApplicable	(	SCIP_READER *	reader,
		const char *	extension
	)

static

returns TRUE, if reader is responsible for files with the given extension

Parameters

reader	reader
extension	extension of the input file name

SCIP_RETCODE SCIPreaderRead	(	SCIP_READER *	reader,
		SCIP_SET *	set,
		const char *	filename,
		const char *	extension,
		SCIP_RESULT *	result
	)

reads problem data from file with given reader or returns SCIP_DIDNOTRUN

Note: we need temporary clock to measure the reading time correctly since in case of creating a new problem within the reader all clocks are reset (including the reader clocks); this resetting is necessary for example for those case we people solve several problems using the (same) interactive shell

Parameters

reader	reader
set	global SCIP settings
filename	name of the input file
extension	extension of the input file name
result	pointer to store the result of the callback method

writes problem data to file with given reader or returns SCIP_DIDNOTRUN

Parameters

reader	reader
prob	problem data
set	global SCIP settings
file	output file (or NULL for standard output)
extension	file format
genericnames	using generic variable and constraint names?
result	pointer to store the result of the callback method
