Detailed Description

Irregular Swaption class.

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.
