Constructors
See the TermStructure documentation for issues regarding constructors.


SwaptionVolatilityStructure (const Calendar &calendar, BusinessDayConvention bdc, const DayCounter &dc=DayCounter())
default constructor
SwaptionVolatilityStructure (const Date &referenceDate, const Calendar &calendar, BusinessDayConvention bdc, const DayCounter &dc=DayCounter())

Detailed Description

Swaption-volatility structure

This abstract class defines the interface of concrete swaption volatility structures which will be derived from this one.

Constructor & Destructor Documentation

SwaptionVolatilityStructure (const Calendar & calendar, BusinessDayConvention bdc, const DayCounter & dc = DayCounter())

default constructor

Warning

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