Function Documentation

SCIP_RETCODE SCIPincludeObjReader	(	SCIP *	scip,
		scip::ObjReader *	objreader,
		SCIP_Bool	deleteobject
	)

creates the file reader for the given file reader object and includes it in SCIP

The method should be called in one of the following ways:

1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyReader* myreader = new MyReader(...); SCIP_CALL( SCIPincludeObjReader(scip, &myreader, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete myreader; // delete reader AFTER SCIPfree() !

1. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjReader(scip, new MyReader(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyReader is called here

Parameters

scip	SCIP data structure
objreader	file reader object
deleteobject	should the reader object be deleted when reader is freed?

scip::ObjReader* SCIPfindObjReader	(	SCIP *	scip,
		const char *	name
	)

returns the reader object of the given name, or 0 if not existing

Parameters

scip	SCIP data structure
name	name of file reader

scip::ObjReader* SCIPgetObjReader	(	SCIP *	scip,
		SCIP_READER *	reader
	)

returns the reader object for the given file reader

Parameters

scip	SCIP data structure
reader	file reader
