Method Detail

survivalProbabilities

public LegalEntitySurvivalProbabilities survivalProbabilities(StandardId legalEntityId,
                                                              Currency currency)

Description copied from interface: CreditRatesProvider

Gets the survival probabilities for a standard ID and a currency.

If both the standard ID and currency are matched, the relevant LegalEntitySurvivalProbabilities is returned.

If the valuation date is on the specified date, the survival probability is 1.

Specified by:

survivalProbabilities in interface CreditRatesProvider

Parameters:

legalEntityId - the standard ID of legal entity to get the discount factors for

currency - the currency to get the discount factors for

Returns:

the survival probabilities

discountFactors

public CreditDiscountFactors discountFactors(Currency currency)

Description copied from interface: CreditRatesProvider

Gets the discount factors for a currency.

The discount factor represents the time value of money for the specified currency when comparing the valuation date to the specified date.

If the valuation date is on the specified date, the discount factor is 1.

Specified by:

discountFactors in interface CreditRatesProvider

Parameters:

currency - the currency to get the discount factors for

Returns:

the discount factors for the specified currency

recoveryRates

public RecoveryRates recoveryRates(StandardId legalEntityId)

Description copied from interface: CreditRatesProvider

Gets the recovery rates for a standard ID.

If both the standard ID and currency are matched, the relevant RecoveryRates is returned.

Specified by:

recoveryRates in interface CreditRatesProvider

Parameters:

legalEntityId - the standard ID of legal entity to get the discount factors for

Returns:

the recovery rates

parameterSensitivity

public CurrencyParameterSensitivities parameterSensitivity(PointSensitivities pointSensitivities)

Description copied from interface: CreditRatesProvider

Computes the parameter sensitivity.

This computes the CurrencyParameterSensitivities associated with the PointSensitivities. This corresponds to the projection of the point sensitivity to the curve internal parameters representation.

The sensitivities handled here are CreditCurveZeroRateSensitivity, ZeroRateSensitivity. For the other sensitivity objects, use RatesProvider instead.

Specified by:

parameterSensitivity in interface CreditRatesProvider

Parameters:

pointSensitivities - the point sensitivity

Returns:

the sensitivity to the curve parameters

singleCreditCurveParameterSensitivity

public CurrencyParameterSensitivity singleCreditCurveParameterSensitivity(PointSensitivities pointSensitivities,
                                                                          StandardId legalEntityId,
                                                                          Currency currency)

Description copied from interface: CreditRatesProvider

Computes the parameter sensitivity for a specific credit curve.

The credit curve is specified by legalEntityId and currency.

Specified by:

singleCreditCurveParameterSensitivity in interface CreditRatesProvider

Parameters:

pointSensitivities - the point sensitivity

legalEntityId - the legal entity

currency - the currency

Returns:

the sensitivity to the curve parameters

singleDiscountCurveParameterSensitivity

public CurrencyParameterSensitivity singleDiscountCurveParameterSensitivity(PointSensitivities pointSensitivities,
                                                                            Currency currency)

Description copied from interface: CreditRatesProvider

Computes the parameter sensitivity for a specific discount curve.

The discount curve is specified by currency.

Specified by:

singleDiscountCurveParameterSensitivity in interface CreditRatesProvider

Parameters:

pointSensitivities - the point sensitivity

currency - the currency

Returns:

the sensitivity to the curve parameters

findData

public <T> Optional<T> findData(MarketDataName<T> name)

Description copied from interface: CreditRatesProvider

Finds the market data with the specified name.

This is most commonly used to find a Curve using a CurveName. If the market data cannot be found, empty is returned.

Specified by:

findData in interface CreditRatesProvider

Type Parameters:

T - the type of the market data value

Parameters:

name - the name to find

Returns:

the market data value, empty if not found
