Inheritance diagram for BlackVolTermStructure:

Detailed Description
Black-volatility term structure.This abstract class defines the interface of concrete Black-volatility term structures which will be derived from this one.
Volatilities are assumed to be expressed on an annual basis.

Constructors | |
See the TermStructure documentation for issues regarding constructors. | |
BlackVolTermStructure (const DayCounter &dc=Actual365Fixed()) | |
default constructor | |
BlackVolTermStructure (const Date &referenceDate, const Calendar &cal=Calendar(), const DayCounter &dc=Actual365Fixed()) | |
initialize with a fixed reference date | |
BlackVolTermStructure (Natural settlementDays, const Calendar &, const DayCounter &dc=Actual365Fixed()) | |
calculate the reference date based on the global evaluation date | |
Black Volatility | |
Volatility | blackVol (const Date &maturity, Real strike, bool extrapolate=false) const |
present (a.k.a spot) volatility | |
Volatility | blackVol (Time maturity, Real strike, bool extrapolate=false) const |
present (a.k.a spot) volatility | |
Real | blackVariance (const Date &maturity, Real strike, bool extrapolate=false) const |
present (a.k.a spot) variance | |
Real | blackVariance (Time maturity, Real strike, bool extrapolate=false) const |

future (a.k.a. forward) variance | |
Real | blackForwardVariance (Time time1, Time time2, Real strike, bool extrapolate=false) const |
future (a.k.a. forward) variance | |
Limits | |
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 | |
Visitability | |
virtual void | accept (AcyclicVisitor &) |

Calculations | |
These methods must be implemented in derived classes to perform the actual volatility calculations. When they are called, range check has already been performed; therefore, they must assume that extrapolation is required. | |
virtual Real | blackVarianceImpl (Time t, Real strike) const =0 |
Black variance calculation. | |
virtual Volatility | blackVolImpl (Time t, Real strike) const =0 |
Black volatility calculation. |

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