Cap/floor at-the-money term-volatility vector.
This class provides the at-the-money volatility for a given cap/floor interpolating a volatility vector whose elements are the market volatilities of a set of caps/floors with given length.

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.

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