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. | |

Detailed Description
Black at-the-money (no-smile) volatility curve.
This abstract class defines the interface of concrete Black at-the-money (no-smile) volatility curves which will be derived from this one.
Volatilities are assumed to be expressed on an annual basis.
