public class IdentityCalculator
extends UnaryCalculator

Identity calculators are unary calculators that directly let probe measurements pass through. For example, the current state of a "take passive resource state probe" may directly be passed through in order to determine its utilization.

calculate

protected org.palladiosimulator.measurementframework.MeasuringValue calculate(List<ProbeMeasurement> probeMeasurements)
                                                                       throws CalculatorException

This calculation directly lets a single probe measurement pass through. TODO Update JavaDoc

Specified by:

calculate in class Calculator

Parameters:

probeMeasurements - The list of probe measurements is expected to contain a single measurement of type TupleMeasurement.

Returns:

The probe measurement value wrapped in a measurement.

Throws:

CalculatorException - In case the received probe measurements do not conform to the specified metric
