Constructor Detail

DiscountCurveRenormalized

public DiscountCurveRenormalized(String name,
                                 LocalDate referenceDate,
                                 LocalDate spotDate,
                                 String baseCurveName)

Method Detail

getName

public String getName()

Description copied from interface: Curve

Get the name of the curve.

Specified by:

getName in interface Curve

Returns:

The name of this curve

getReferenceDate

public LocalDate getReferenceDate()

Description copied from interface: Curve

Return the reference date of this curve, i.e. the date associated with t=0. May be null in case the curve is not associated with a fixed date (e.g. a time homogenous model).

Specified by:

getReferenceDate in interface Curve

Returns:

The date identified as t=0.

getValue

public double getValue(double time)

Description copied from interface: Curve

Returns the value for the time using the interpolation method associated with this curve.

Specified by:

getValue in interface Curve

Parameters:

time - Time for which the value should be returned.

Returns:

The value at the give time.

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.

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.

getCloneForParameter

public Curve getCloneForParameter(double[] value)
                           throws CloneNotSupportedException

Description copied from interface: ParameterObject

Create a clone with a modified parameter.

Specified by:

getCloneForParameter in interface ParameterObject

Specified by:

getCloneForParameter in interface Curve

Parameters:

value - The new parameter.

Returns:

A clone with an otherwise modified parameter.

Throws:

CloneNotSupportedException - Thrown, when the curve could not be cloned.

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.

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.

clone

public DiscountCurveRenormalized clone()

Description copied from interface: Curve

Create a deep copied clone.

Specified by:

clone in interface Curve

Overrides:

clone in class Object

Returns:

A clone (deep copied).
