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. | |

Black-volatility term structure.
This abstract class defines the interface of concrete Black-volatility term structures which will be derived from this one.
Volatilities are assumed to be expressed on an annual basis.
