◆ setupArguments()
|
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.
Definition at line 69 of file irregularswap.cpp.
Here is the call graph for this function:
◆ fetchResults()
|
overridevirtual |
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.
Definition at line 174 of file irregularswap.cpp.
Here is the call graph for this function:
◆ setupExpired()
|
overrideprivatevirtual |
This method must leave the instrument in a consistent state when the expiration condition is met.
