public class CDSComponent
extends CreditDefaultSwap

CDSComponent implements the credit default swap product contract details. It exposes the following functionality:

• Methods to extract effective date, maturity date, coupon, coupon day count, coupon frequency, contingent credit, currency, basket notional, credit valuation parameters, and optionally the outstanding notional schedule.
• Methods to compute the Jacobians to/from quote-to-latent state/manifest measures
• Serialization into and de-serialization out of byte arrays
• CDS specific methods such as such loss metric/Jacobian estimation, quote flat spread calibration etc:

• Module = Product Core Module
• Library = Fixed Income Analytics
• Project = Product Components/Baskets for Credit, FRA, FX, Govvie, Rates, and Option AssetClasses
• Package = Credit Products - Components and Baskets
