Member Function Documentation
void setupArguments (PricingEngine::arguments *) const [virtual]
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.
void fetchResults (const PricingEngine::results * r) const [virtual]
When a derived result structure is defined for an instrument, this method should be overridden to read from it. This is mandatory in case a pricing engine is used.
Reimplemented from Instrument.
void setupExpired () const [protected, virtual]
This method must leave the instrument in a consistent state when the expiration condition is met.
Reimplemented from Instrument.
