CompositeInstrument — Composite instrument
Public Member Functions
void add (const boost::shared_ptr< Instrument > &instrument, Real multiplier=1.0)
adds an instrument to the composite
void subtract (const boost::shared_ptr< Instrument > &instrument, Real multiplier=1.0)
shorts an instrument from the composite
void deepUpdate ()
bool isExpired () const
returns whether the instrument might have value greater than zero.
void performCalculations () const
Additional Inherited Members
This instrument is an aggregate of other instruments. Its NPV is the sum of the NPVs of its components, each possibly multiplied by a given factor.
Example: static replication of a down-and-out barrier option
Methods that drive the calculation directly (such as recalculate(), freeze() and others) might not work correctly.
Member Function Documentation
void deepUpdate () [virtual]
This method allows to explicitly update the instance itself and nested observers. If notifications are disabled a call to this method ensures an update of such nested observers. It should be implemented in derived classes whenever applicable
Reimplemented from Observer.
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 from Instrument.
