public interface DiscountCurve
extends Curve
```
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(AnalyticModel 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.
