Detailed Description

Optionlet (caplet/floorlet) volatility structure.

This class is purely abstract and defines the interface of concrete structures which will be derived from this one.

Constructor & Destructor Documentation

◆ OptionletVolatilityStructure() [1/3]

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 optionletvolatilitystructure.cpp.

◆ OptionletVolatilityStructure() [2/3]

OptionletVolatilityStructure ( const Date referenceDate,
const Calendar cal,
BusinessDayConvention  bdc,
const DayCounter dc = DayCounter() 
)

initialize with a fixed reference date

Definition at line 30 of file optionletvolatilitystructure.cpp.

◆ OptionletVolatilityStructure() [3/3]

OptionletVolatilityStructure ( Natural  settlementDays,
const Calendar cal,
BusinessDayConvention  bdc,
const DayCounter dc = DayCounter() 
)

calculate the reference date based on the global evaluation date
