public final class ImmutableLegalEntityDiscountingProvider
extends Object
implements LegalEntityDiscountingProvider, org.joda.beans.ImmutableBean, Serializable

An immutable provider of data for bond pricing, based on repo and issuer discounting.

This used to price bonds issued by a legal entity. The data to do this includes discount factors of repo curves and issuer curves. If the bond is inflation linked, the price index data is obtained from RatesProvider.

Two types of discount factors are provided by this class. Repo curves are looked up using either the security ID of the bond, or the issuer (legal entity). Issuer curves are only looked up using the issuer (legal entity).

Method Detail

repoCurveDiscountFactors

public RepoCurveDiscountFactors repoCurveDiscountFactors(SecurityId securityId,
                                                         LegalEntityId issuerId,
                                                         Currency currency)

Description copied from interface: LegalEntityDiscountingProvider

Gets the discount factors from a repo curve based on the security ID, issuer ID and currency.

This searches first for a curve associated with the security iD and currency, and then for a curve associated with the issuer ID and currency.

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

Specified by:

repoCurveDiscountFactors in interface LegalEntityDiscountingProvider

Parameters:

securityId - the standard ID of security to get the discount factors for

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

currency - the currency to get the discount factors for

Returns:

the discount factors

repoCurveDiscountFactors

public RepoCurveDiscountFactors repoCurveDiscountFactors(LegalEntityId issuerId,
                                                         Currency currency)

Description copied from interface: LegalEntityDiscountingProvider

Gets the discount factors from a repo curve based on the issuer ID and currency.

This searches for a curve associated with the issuer ID and currency.

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

Specified by:

repoCurveDiscountFactors in interface LegalEntityDiscountingProvider

Parameters:

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

currency - the currency to get the discount factors for

Returns:

the discount factors

issuerCurveDiscountFactors

public IssuerCurveDiscountFactors issuerCurveDiscountFactors(LegalEntityId issuerId,
                                                             Currency currency)

Description copied from interface: LegalEntityDiscountingProvider

Gets the discount factors from an issuer based on the issuer ID and currency.

This searches for a curve associated with the issuer ID and currency.

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

Specified by:

issuerCurveDiscountFactors in interface LegalEntityDiscountingProvider

Parameters:

issuerId - the standard ID to get the discount factors for

currency - the currency to get the discount factors for

Returns:

the discount factors

parameterSensitivity

public CurrencyParameterSensitivities parameterSensitivity(PointSensitivities pointSensitivities)

Description copied from interface: LegalEntityDiscountingProvider

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.

This method handles RepoCurveZeroRateSensitivity and IssuerCurveZeroRateSensitivity. For other sensitivity objects, see RatesProvider.parameterSensitivity(PointSensitivities).

Specified by:

parameterSensitivity in interface LegalEntityDiscountingProvider

Parameters:

pointSensitivities - the point sensitivity

Returns:

the sensitivity to the curve parameters

data

public <T> T data(MarketDataId<T> id)

Description copied from interface: LegalEntityDiscountingProvider

Gets market data of a specific type.

This is a general purpose mechanism to obtain market data. In general, it is desirable to pass the specific market data needed for pricing into the pricing method. However, in some cases, notably swaps, this is not feasible. It is strongly recommended to clearly state on pricing methods what data is required.

Specified by:

data in interface LegalEntityDiscountingProvider

Type Parameters:

T - the type of the value

Parameters:

id - the identifier to find

Returns:

the data associated with the key

findData

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

Description copied from interface: LegalEntityDiscountingProvider

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 LegalEntityDiscountingProvider

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

toImmutableLegalEntityDiscountingProvider

public ImmutableLegalEntityDiscountingProvider toImmutableLegalEntityDiscountingProvider()

Description copied from interface: LegalEntityDiscountingProvider

Returns:

the equivalent immutable legal entity provider
