public interface DiscountCurveInterface
extends CurveInterface

The interface which is implemented by discount curves. A discount curve is a mapping of T to df(T) where df(T) represents the present value of a cash flow or 1 in time T, with respect to a specific currency unit and collateralization.

Method Detail

getDiscountFactor

double getDiscountFactor(double maturity)

Returns the discount factor for the corresponding maturity. This getter is not optimized for performance.

Parameters:

maturity - The maturity for which the discount factor is requested.

Returns:

The discount factor (i.e., price of the zero coupon bond with given maturity and notional 1.

getDiscountFactor

double getDiscountFactor(AnalyticModelInterface model,
                         double maturity)

Returns the discount factor for the corresponding maturity. This getter is not optimized for performance.

Parameters:

model - An analytic model providing a context. Some curves do not need this (can be null).

maturity - The maturity for which the discount factor is requested.

Returns:

The discount factor (i.e., price of the zero coupon bond with given maturity and notional 1.
