## Detailed Description

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.

## 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.
