Constructor & Destructor Documentation

◆ CallableBondVolatilityStructure() [1/3]

CallableBondVolatilityStructure	(	const DayCounter &	dc = `DayCounter()`,
		BusinessDayConvention	bdc = `Following`
	)

default constructor

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

Definition at line 25 of file callablebondvolstructure.cpp.

◆ CallableBondVolatilityStructure() [2/3]

CallableBondVolatilityStructure	(	const Date &	referenceDate,
		const Calendar &	calendar = `Calendar()`,
		const DayCounter &	dc = `DayCounter()`,
		BusinessDayConvention	bdc = `Following`
	)

initialize with a fixed reference date

Definition at line 30 of file callablebondvolstructure.cpp.

◆ CallableBondVolatilityStructure() [3/3]

CallableBondVolatilityStructure	(	Natural	settlementDays,
		const Calendar &	calendar,
		const DayCounter &	dc = `DayCounter()`,
		BusinessDayConvention	bdc = `Following`
	)

calculate the reference date based on the global evaluation date
