Interface RatesMarketDataLookup

  • All Superinterfaces:
    CalculationParameter, FxRateLookup
    public interface RatesMarketDataLookup
extends FxRateLookup, CalculationParameter
    The lookup that provides access to rates in market data.

    The rates market lookup provides access to discount curves and forward curves. This includes Ibor index rates, Overnight index rates, Price index rates, FX rates and discounting.

    The lookup implements CalculationParameter and is used by passing it as an argument to CalculationRules. It provides the link between the data that the function needs and the data that is available in ScenarioMarketData.

    Implementations of this interface must be immutable.

    • Method Detail

      • of

        static RatesMarketDataLookup of​(Map<Currency,​CurveId> discountCurveIds,
                                Map<Index,​CurveId> forwardCurveIds)
        Obtains an instance based on a map of discount and forward curve identifiers.

        The discount and forward curves refer to the curve identifier. The curves themselves are provided in ScenarioMarketData using CurveId as the identifier.

        Parameters:
        discountCurveIds - the discount curve identifiers, keyed by currency
        forwardCurveIds - the forward curves identifiers, keyed by index
        Returns:
        the rates lookup containing the specified curves

      • of

        static RatesMarketDataLookup of​(Map<Currency,​CurveId> discountCurveIds,
                                Map<Index,​CurveId> forwardCurveIds,

                                FxRateLookup fxLookup)
        Obtains an instance based on a map of discount and forward curve identifiers, specifying the source of FX rates.

        The discount and forward curves refer to the curve identifier. The curves themselves are provided in ScenarioMarketData using CurveId as the identifier. The source of market data is rarely needed, as most applications use only one underlying data source.

        Parameters:
        discountCurveIds - the discount curve identifiers, keyed by currency
        forwardCurveIds - the forward curves identifiers, keyed by index
        obsSource - the source of market data for quotes and other observable market data
        fxLookup - the lookup used to obtain FX rates
        Returns:
        the rates lookup containing the specified curves
