Detailed Description

Irregular Swaption class.

Constructor & Destructor Documentation

◆ IrregularSwaption()

IrregularSwaption ( ext::shared_ptr< IrregularSwap swap,
const ext::shared_ptr< Exercise > &  exercise,
IrregularSettlement::Type  delivery = IrregularSettlement::Physical 
)

Definition at line 99 of file irregularswaption.cpp.

Member Function Documentation

◆ isExpired()

bool isExpired ( ) const
overridevirtual

returns whether the instrument might have value greater than zero.

Implements Instrument.

◆ setupArguments()

void setupArguments ( PricingEngine::arguments ) const
overridevirtual

When a derived argument structure is defined for an instrument, this method should be overridden to fill it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

◆ settlementType()

IrregularSettlement::Type settlementType ( ) const

Definition at line 61 of file irregularswaption.hpp.

◆ type()

Swap::Type type ( ) const

Definition at line 62 of file irregularswaption.hpp.

◆ underlyingSwap()

const ext::shared_ptr< IrregularSwap > & underlyingSwap ( ) const

Definition at line 63 of file irregularswaption.hpp.
