Calculations

This method must be implemented in derived classes to perform the actual volatility calculations. When it is called, time check has already been performed; therefore, it must assume that time-extrapolation is allowed.

Detailed Description

Black volatility (smile) surface.

This abstract class defines the interface of concrete Black volatility (smile) surface 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.
