Class ForwardOvernightAveragedDailyRateComputationFn

java.lang.Object

com.opengamma.strata.pricer.impl.rate.ForwardOvernightAveragedDailyRateComputationFn

All Implemented Interfaces:

RateComputationFn<OvernightAveragedDailyRateComputation>

public class ForwardOvernightAveragedDailyRateComputationFn
extends Object
implements RateComputationFn<OvernightAveragedDailyRateComputation>

Rate computation implementation for an averaged daily rate for a single Overnight index.

The rate computation retrieves the rate at each fixing date in the period from the RatesProvider and average them.

Method Detail

rate

public double rate(OvernightAveragedDailyRateComputation computation,
                   LocalDate startDate,
                   LocalDate endDate,
                   RatesProvider provider)

Description copied from interface: RateComputationFn

Determines the applicable rate for the computation.

Each type of rate has specific rules, encapsulated in RateComputation.

The start date and end date refer to the accrual period. In many cases, this information is not necessary, however it does enable some implementations that would not otherwise be possible.

Specified by:

rate in interface RateComputationFn<OvernightAveragedDailyRateComputation>

Parameters:

computation - the computation definition

startDate - the start date of the accrual period

endDate - the end date of the accrual period

provider - the rates provider

Returns:

the applicable rate

rateSensitivity

public PointSensitivityBuilder rateSensitivity(OvernightAveragedDailyRateComputation computation,
                                               LocalDate startDate,
                                               LocalDate endDate,
                                               RatesProvider provider)

Description copied from interface: RateComputationFn

Determines the point sensitivity for the rate computation.

This returns a sensitivity instance referring to the curves used to determine each forward rate.

Specified by:

rateSensitivity in interface RateComputationFn<OvernightAveragedDailyRateComputation>

Parameters:

computation - the computation definition

startDate - the start date of the accrual period

endDate - the end date of the accrual period

provider - the rates provider

Returns:

the point sensitivity

explainRate

public double explainRate(OvernightAveragedDailyRateComputation computation,
                          LocalDate startDate,
                          LocalDate endDate,
                          RatesProvider provider,
                          ExplainMapBuilder builder)

Description copied from interface: RateComputationFn

Explains the calculation of the applicable rate.

This adds information to the ExplainMapBuilder to aid understanding of the computation. The actual rate is also returned.

Specified by:

explainRate in interface RateComputationFn<OvernightAveragedDailyRateComputation>

Parameters:

computation - the computation definition

startDate - the start date of the accrual period

endDate - the end date of the accrual period

provider - the rates provider

builder - the builder to populate

Returns:

the applicable rate
