Detailed Description
Swaption-volatility structureThis class is purely abstract and defines the interface of concrete swaption volatility structures which will be derived from this one.
Public Member Functions | |
virtual std::pair< Time, Time > | convertDates (const Date &optionDate, const Period &swapTenor) const |
implements the conversion between dates and times | |
virtual BusinessDayConvention | businessDayConvention () const |
the business day convention used for option date calculation | |
Date | optionDateFromTenor (const Period &optionTenor) const |
implements the conversion between optionTenors and optionDates | |
Constructors | |
See the TermStructure documentation for issues regarding constructors. | |
SwaptionVolatilityStructure (const DayCounter &dc=Actual365Fixed(), BusinessDayConvention bdc=Following) | |
default constructor | |
SwaptionVolatilityStructure (const Date &referenceDate, const Calendar &calendar=Calendar(), const DayCounter &dc=Actual365Fixed(), BusinessDayConvention bdc=Following) | |
initialize with a fixed reference date | |
SwaptionVolatilityStructure (Natural settlementDays, const Calendar &, const DayCounter &dc=Actual365Fixed(), BusinessDayConvention bdc=Following) | |
calculate the reference date based on the global evaluation date | |
Volatility, variance and smile | |

- Warning:
- term structures initialized by means of this constructor must manage their own reference date by overriding the referenceDate() method.
