Function Documentation

SCIPincludeObjConshdlr()

SCIP_RETCODE SCIPincludeObjConshdlr	(	SCIP *	scip,
		scip::ObjConshdlr *	objconshdlr,
		SCIP_Bool	deleteobject
	)

creates the constraint handler for the given constraint handler 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) ); ... MyConshdlr* myconshdlr = new MyConshdlr(...); SCIP_CALL( SCIPincludeObjConshdlr(scip, &myconshdlr, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete myconshdlr; // delete conshdlr AFTER SCIPfree() !
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjConshdlr(scip, new MyConshdlr(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyConshdlr is called here

creates the constraint handler for the given constraint handler object and includes it in SCIP

Parameters

scip	SCIP data structure
objconshdlr	constraint handler object
deleteobject	should the constraint handler object be deleted when conshdlr is freed?
