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
This abstract class defines the interface of concrete local-volatility term structures 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.
