Function Documentation

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

Parameters

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

scip::ObjConshdlr* SCIPfindObjConshdlr	(	SCIP *	scip,
		const char *	name
	)

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

Parameters

scip	SCIP data structure
name	name of constraint handler

scip::ObjConshdlr* SCIPgetObjConshdlr	(	SCIP *	scip,
		SCIP_CONSHDLR *	conshdlr
	)

returns the conshdlr object for the given constraint handler

Parameters

scip	SCIP data structure
conshdlr	constraint handler
