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

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.
