Abstract instrument class.
This class is purely abstract and defines the interface of concrete instruments which will be derived from this one.
observability of class instances is checked.
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 in Bond, SyntheticCDO, CallableFixedRateBond, CPISwap, ContinuousPartialFixedLookbackOption, CreditDefaultSwap, FloatFloatSwap, ZeroCouponInflationSwap, VanillaSwap, NthToDefault, YearOnYearInflationSwap, NonstandardSwap, EnergyCommodity, CPICapFloor, ContinuousPartialFloatingLookbackOption, AssetSwap, CallableBond, Swaption, IrregularSwap, CapFloor, YoYInflationCapFloor, DiscreteAveragingAsianOption, VarianceSwap, VanillaSwingOption, ContinuousFixedLookbackOption, VarianceOption, Swap, IrregularSwaption, DividendVanillaOption, ForwardVanillaOption, CdsOption, CliquetOption, WriterExtensibleOption, NonstandardSwaption, MultiAssetOption, HimalayaOption, PagodaOption, BarrierOption, DoubleBarrierOption, PathMultiAssetOption, DividendBarrierOption, FloatFloatSwaption, ContinuousAveragingAsianOption, TwoAssetBarrierOption, VanillaStorageOption, CompoundOption, MargrabeOption, ContinuousFloatingLookbackOption, SimpleChooserOption, and Option.
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 in Bond, SyntheticCDO, CPISwap, CreditDefaultSwap, FloatFloatSwap, ZeroCouponInflationSwap, VanillaSwap, NthToDefault, YearOnYearInflationSwap, NonstandardSwap, EnergyCommodity, CPICapFloor, AssetSwap, IrregularSwap, VarianceSwap, QuantoVanillaOption, Swap, OneAssetOption, ForwardVanillaOption, MultiAssetOption, QuantoDoubleBarrierOption, QuantoBarrierOption, MargrabeOption, and QuantoForwardVanillaOption.
void calculate () const [protected], [virtual]
This method performs all needed calculations by calling the performCalculations method.
Objects cache the results of the previous calculation. Such results will be returned upon later invocations of calculate. When the results depend on arguments which could change between invocations, the lazy object must register itself as observer of such objects for the calculations to be performed again when they change.
Should this method be redefined in derived classes, LazyObject::calculate() should be called in the overriding method.
Reimplemented from LazyObject.
void setupExpired () const [protected], [virtual]
This method must leave the instrument in a consistent state when the expiration condition is met.
Reimplemented in CreditDefaultSwap, Bond, Swap, RiskyBond, VarianceSwap, OneAssetOption, PathMultiAssetOption, and MultiAssetOption.
void performCalculations () const [protected], [virtual]
In case a pricing engine is not used, this method must be overridden to perform the actual calculations and set any needed results. In case a pricing engine is used, the default implementation can be used.
Reimplemented in FixedRateBondForward, Forward, RiskyBond, ConvertibleBond, CompositeInstrument, EnergyVanillaSwap, EnergyBasisSwap, EnergyFuture, and Stock.
