Volatility volatilityImpl (Time t, Rate strike) const
implements the actual volatility calculation in derived classes

Detailed Description

Cap/floor smile volatility surface.

This class provides the volatility for a given cap by interpolating a volatility surface whose elements are the market term volatilities of a set of caps/floors with given length and given strike.

Member Function Documentation

void update () [virtual]

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from LazyObject.

void performCalculations () const [virtual]

This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.
