Detailed Description

Composite instrument

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

Warning

Methods that drive the calculation directly (such as recalculate(), freeze() and others) might not work correctly.

Examples:

Replication.cpp.

Member Function Documentation

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.
