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.

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.

default constructor

Warning

term structures initialized by means of this constructor must manage their own reference date by overriding the referenceDate() method.
