Constructors | |
See the TermStructure documentation for issues regarding constructors. | |
CapVolatilityStructure () | |
default constructor | |
CapVolatilityStructure (const Date &referenceDate) | |
initialize with a fixed reference date | |
CapVolatilityStructure (Integer settlementDays, const Calendar &) | |
calculate the reference date based on the global evaluation date | |
Volatility | |
Volatility | volatility (const Date &end, Rate strike, bool extrapolate=false) const |
Volatility | volatility (const Period &length, Rate strike, bool extrapolate=false) const |
returns the volatility for a given cap/floor length and strike rate | |
Volatility | volatility (Time t, Rate strike, bool extrapolate=false) const |
returns the volatility for a given end time and strike rate | |
Limits | |
virtual Date | maxDate () const =0 |
the latest date for which the term structure can return vols | |
virtual Time | maxTime () const |
the latest time for which the term structure can return vols | |
virtual Real | minStrike () const =0 |
the minimum strike for which the term structure can return vols | |
virtual Real | maxStrike () const =0 |
the maximum strike for which the term structure can return vols | |
Protected Member Functions | |
virtual Volatility | volatilityImpl (Time length, Rate strike) const =0 |
implements the actual volatility calculation in derived classes |
