Inheritance diagram for CapFloor:

Detailed Description
Base class for cap-like instruments.
- Tests:
- the correctness of the returned value is tested by checking that the price of a cap (resp. floor) decreases (resp. increases) with the strike rate.
- the relationship between the values of caps, floors and the resulting collars is checked.
- the put-call parity between the values of caps, floors and swaps is checked.
- the correctness of the returned implied volatility is tested by using it for reproducing the target value.
- the correctness of the returned value is tested by checking it against a known good value.
