Constructors
See the TermStructure documentation for issues regarding constructors.

 CapVolatilityStructure ()
 default constructor
 CapVolatilityStructure (const Date &referenceDate)
 initialize with a fixed reference date
 CapVolatilityStructure (Integer settlementDays, const Calendar &)
 calculate the reference date based on the global evaluation date
Volatility
Volatility volatility (const Date &end, Rate strike, bool extrapolate=false) const
Volatility volatility (const Period &length, Rate strike, bool extrapolate=false) const
 returns the volatility for a given cap/floor length and strike rate
Volatility volatility (Time t, Rate strike, bool extrapolate=false) const
 returns the volatility for a given end time and strike rate
Limits
virtual Date maxDate () const =0
 the latest date for which the term structure can return vols
virtual Time maxTime () const
 the latest time for which the term structure can return vols
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

Protected Member Functions

virtual Volatility volatilityImpl (Time length, Rate strike) const =0
 implements the actual volatility calculation in derived classes

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