DiscountCurveFromProductOfCurves

public DiscountCurveFromProductOfCurves(String name,
 LocalDate referenceDate,
 String... curveNames)

Create a discount curve using one or more curves. The product curve is generated dynamically by looking up the given curveNames in the model passed to the method getDiscountFactor(AnalyticModel, double).

Parameters:

name - The name of this curve.

referenceDate - The reference date of this curve.

curveNames - Argument list or array of curve names.

DiscountCurveFromProductOfCurves

public DiscountCurveFromProductOfCurves(String name,
 LocalDate referenceDate,
 DiscountCurve... curves)

Create a discount curve using one or more given curves.

Parameters:

name - The name of this curve.

referenceDate - The reference date of this curve.

curves - Argument list or array of curves.

Method Details

getDiscountFactor

public double getDiscountFactor(double maturity)

Description copied from interface: DiscountCurve

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

Specified by:

getDiscountFactor in interface DiscountCurve

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

public double getDiscountFactor(AnalyticModel model,
 double maturity)

Description copied from interface: DiscountCurve

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

Specified by:

getDiscountFactor in interface DiscountCurve

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.

getValue

public double getValue(AnalyticModel model,
 double time)

Description copied from interface: Curve

Returns the value for the time using the interpolation method associated with this curve within a given context, i.e., a model. The model (context) is needed only if the curve relies on another curve. Examples are a forward curve which relies on a discount curve or a discount curve which is defined via a spread over another curve.

Specified by:

getValue in interface Curve

Parameters:

model - An analytic model providing a context.

time - Time for which the value should be returned.

Returns:

The value at the give time.

getParameter

public double[] getParameter()

Description copied from interface: ParameterObject

Get the current parameter associated with the state of the objects.

Specified by:

getParameter in interface ParameterObject

Returns:

The parameter.

setParameter

public void setParameter(double[] parameter)

Description copied from interface: ParameterObject

Set the current parameter and change the state of the objects.

Specified by:

setParameter in interface ParameterObject

Parameters:

parameter - The parameter associated with the new state of the objects.

getCloneBuilder

public CurveBuilder getCloneBuilder()

Description copied from interface: Curve

Returns a curve builder bases on a clone of this curve. Using that curve builder you may create a new curve from this curve by adding points or changing properties. Note: The clone has the same name than this one.

Specified by:

getCloneBuilder in interface Curve

Returns:

An object implementing the CurveBuilderInterface where the underlying curve is a clone of this curve.
