Member Function Documentation

◆ isExpired()

bool isExpired ( ) const
overridevirtual

returns whether the instrument might have value greater than zero.

Implements Instrument.

◆ performCalculations()

void performCalculations ( ) const
overrideprotectedvirtual

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.
