Calculations | |
These methods must be implemented in derived classes to perform the actual volatility calculations. When they are called, range check has already been performed; therefore, they must assume that extrapolation is required. | |

virtual |
This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.
Implements Observer.
|
virtual |
This method must implement any calculations which must be (re)done in order to calculate the desired results.
Implements LazyObject.
