Detailed Description
Black-volatility term structure.
This abstract class acts as an adapter to BlackVolTermStructure allowing the programmer to implement only the blackVolImpl(Time, Real, bool) method in derived classes.
Volatility are assumed to be expressed on an annual basis.

Constructor & Destructor Documentation
◆ BlackVolatilityTermStructure() [1/3]
| BlackVolatilityTermStructure | ( | BusinessDayConvention | bdc = Following, |
| 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.

| BlackVolatilityTermStructure | ( | const Date & | referenceDate, |
| const Calendar & | cal = Calendar(), |
||
| BusinessDayConvention | bdc = Following, |
||
| const DayCounter & | dc = DayCounter() |
||
| ) |
initialize with a fixed reference date

| const Calendar & | cal, | ||
| BusinessDayConvention | bdc = Following, |
||
| const DayCounter & | dc = DayCounter() |
