| 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 from Instrument.
| 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 from Instrument.
| Rate fairUpfront | ( | ) | const | 
Returns the upfront spread that, given the running spread and the quoted recovery rate, will make the instrument have an NPV of 0.
| Rate fairSpread | ( | ) | const | 
Returns the running spread that, given the quoted recovery rate, will make the running-only CDS have an NPV of 0.
| Real couponLegBPS | ( | ) | const | 
Returns the variation of the fixed-leg value given a one-basis-point change in the running spread.

Conventional/standard upfront-to-spread conversion.
Under a standard ISDA model and a set of standardised instrument characteristics, it is the running only quoted spread that will make a CDS contract have an NPV of 0 when quoted for that running only spread. Refer to: "ISDA Standard CDS converter specification." May 2009.
The conventional recovery rate to apply in the calculation is as specified by ISDA, not necessarily equal to the market-quoted one. It is typically 0.4 for SeniorSec and 0.2 for subordinate.
| void setupExpired | ( | ) | const  [protected, virtual] | 
This method must leave the instrument in a consistent state when the expiration condition is met.
