Class BondCurve

  • All Implemented Interfaces:
    Serializable, Cloneable, ParameterObject, Curve

    public class BondCurve
    extends AbstractCurve
    Implements the bond curve as a curve object, see Curve. The bond curve is built as a product of a given reference discount curve and spread curve. Since it is not clear in general if the reference curve or the spread curve are given in terms of discount factors or zero rates, this class distinguishes between all possible cases of types. For the curve types provided see BondCurve.Type.

        public BondCurve​(String name,
                         LocalDate referenceDate,
                         Curve referenceCurve,

        Creates a bond curve.
        Parameters:
        name - Name of the curve.
        referenceDate - The reference date for this curve, i.e., the date which defined t=0.
        referenceCurve - The reference discount curve.
        spreadCurve - The given spread curve.
        type - The types of the given curves "referenceCurve" and "spreadCurve" (discount factor or zero rate)

      • 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
        Overrides:
        getValue in class AbstractCurve
        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.
        Parameters:
        model - An analytic model providing a context.
        time - Time for which the value should be returned.
        Returns:
        The value at the give time.
      • getDiscountFactor

        public double getDiscountFactor​(double time)
      • getDiscountFactor

        public double getDiscountFactor​(AnalyticModel model,
                                        double time)
      • getZeroRate

        public double getZeroRate​(double maturity)
        Returns the zero rate for a given maturity, i.e., -ln(df(T)) / T where T is the given maturity and df(T) is the discount factor at time $T$.
        Parameters:
        maturity - The given maturity.
        Returns:
        The zero rate.
      • getCloneBuilder

        public CurveBuilder getCloneBuilder()
                                     throws CloneNotSupportedException
        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.
        Returns:
        An object implementing the CurveBuilderInterface where the underlying curve is a clone of this curve.
        Throws:
        CloneNotSupportedException - Thrown, when this curve could not be cloned.
      • getName

        public String getName()
        Description copied from interface: Curve
        Get the name of the curve.
        Specified by:
        getName in interface Curve
        Overrides:
        getName in class AbstractCurve
        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
        Overrides:
        getReferenceDate in class AbstractCurve
        Returns:
        The date identified as t=0.
