SCIPincludeObjReader()

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

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 responsible 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() !
2. 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?
