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. | |

Constant local volatility, no time-strike dependence.
This class implements the LocalVolatilityTermStructure interface for a constant local volatility (no time/asset dependence). Local volatility and Black volatility are the same when volatility is at most time dependent, so this class is basically a proxy for BlackVolatilityTermStructure.
