(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called. | |

Abstract base class for objects responsible for updating the Hessian information.
This can be done using exact second derivatives from the NLP, or by a quasi-Newton Option. The result is put into the W field in IpData.
