```
public class CdsIndexTradeCalculationFunction
extends Object
implements CalculationFunction<CdsIndexTrade>
```

  - targetType
```
public Class<CdsIndexTrade> targetType()
```
    Description copied from interface: CalculationFunction
    
    Gets the target type that this function applies to.
    The target type will typically be a concrete class.
    
    Specified by:
    
    targetType in interface CalculationFunction<CdsIndexTrade>
    
    Returns:
    
    the target type
  - supportedMeasures
```
public Set<Measure> supportedMeasures()
```
    Description copied from interface: CalculationFunction
    
    Returns the set of measures that the function can calculate.
    
    Specified by:
    
    supportedMeasures in interface CalculationFunction<CdsIndexTrade>
    
    Returns:
    
    the read-only set of measures that the function can calculate
  - identifier
```
public Optional<String> identifier(CdsIndexTrade target)
```
    Description copied from interface: CalculationFunction
    
    Returns an identifier that should uniquely identify the specified target.
    This identifier is used in error messages to identify the target. This should normally be overridden to provide a suitable identifier. For example, if the target is a trade, there will typically be a trade identifier available.
    This method must not throw an exception.
    
    Specified by:
    
    identifier in interface CalculationFunction<CdsIndexTrade>
    
    Parameters:
    
    target - the target of the calculation
    
    Returns:
    
    the identifier of the target, empty if no suitable identifier available
  - naturalCurrency
```
public Currency naturalCurrency(CdsIndexTrade trade,
                                ReferenceData refData)
```
    Description copied from interface: CalculationFunction
    
    Returns the "natural" currency for the specified target.
    This is the currency to which currency amounts are converted if the "natural" reporting currency is requested using ReportingCurrency.NATURAL. Most targets have a "natural" currency, for example the currency of a FRA or the base currency of an FX forward.
    It is required that all functions that return a currency-convertible measure must choose a "natural" currency for each trade. The choice must be consistent not random, given the same trade the same currency must be returned. This might involve picking, the first leg or base currency from a currency pair. An exception must only be thrown if the function handles no currency-convertible measures.
    
    Specified by:
    
    naturalCurrency in interface CalculationFunction<CdsIndexTrade>
    
    Parameters:
    
    trade - the target of the calculation
    
    refData - the reference data to be used in the calculation
    
    Returns:
    
    the "natural" currency of the target

public FunctionRequirements requirements(CdsIndexTrade trade,
                                         Set<Measure> measures,
                                         CalculationParameters parameters,
                                         ReferenceData refData)
```
    Description copied from interface: CalculationFunction
    
    Determines the market data required by this function to perform its calculations.
    Any market data needed by the calculate method should be specified.
    The set of measures may include measures that are not supported by this function.
    
    Specified by:
    
    requirements in interface CalculationFunction<CdsIndexTrade>
    
    Parameters:
    
    trade - the target of the calculation
    
    measures - the set of measures to be calculated
    
    parameters - the parameters that affect how the calculation is performed
    
    refData - the reference data to be used in the calculation
    
    Returns:
    
    the requirements specifying the market data the function needs to perform calculations

public Map<Measure,Result<?>> calculate(CdsIndexTrade trade,
                                              Set<Measure> measures,
                                              CalculationParameters parameters,
                                              ScenarioMarketData scenarioMarketData,
                                              ReferenceData refData)
```
    Description copied from interface: CalculationFunction
    
    Calculates values of multiple measures for the target using multiple sets of market data.
    The set of measures must only contain measures that the function supports, as returned by CalculationFunction.supportedMeasures(). The market data must provide at least the set of data requested by CalculationFunction.requirements(CalculationTarget, Set, CalculationParameters, ReferenceData).
    The result of this method will often be an instance of ScenarioArray, which handles the common case where there is one calculated value for each scenario. However, it is also possible for the function to calculate an aggregated result, such as the maximum or minimum value across all scenarios, in which case the result would not implement ScenarioArray.
    
    Specified by:
    
    calculate in interface CalculationFunction<CdsIndexTrade>
    
    Parameters:
    
    trade - the target of the calculation
    
    measures - the set of measures to calculate
    
    parameters - the parameters that affect how the calculation is performed
    
    scenarioMarketData - the multi-scenario market data to be used in the calculation
    
    refData - the reference data to be used in the calculation
    
    Returns:
    
    the read-only map of calculated values, keyed by their measure
