Detailed Description

The algorithm and the operation the algorithm belongs to are responsible to update the statistical information. Note, that a stemod::core::AlgorithmMeasurement object is used for the execution time measurement on the user side and automatically triggers the insertion of a new MeasurementPair as soon as the measurement is stopped.

Internally, stemod::core::AlgorithmMeasurement::afterAlgorithmExecution() stops the time and adds the received data to the algorithms statistics.
