    • Method Detail

      • addMeasurementRange

        public static MeasurementRange addMeasurementRange​(Measurement measurement)
        Creates a new MeasurementRange and contained elements if there are already existing elements in another MeasurementRange. Does not set the startTime and endTime properties.
        Parameters:
        measurement - Location where to add the range.
        Returns:
        The newly created measurement range.

      • createDAOsForRawMeasurements

        public static void createDAOsForRawMeasurements​(RawMeasurements rm)
        Creates the DAOs for the data series of a raw measurement.
        Parameters:
        rm - The raw measurements containing the data series.

      • storeMeasurement

        public static void storeMeasurement​(Measurement measurement,
                                    org.palladiosimulator.measurementframework.MeasuringValue measuringValue)
        Stores a new measurement at the last existing range.
        Parameters:
        measuringValue - The measurement of the experiment run for which a new measurement exists.
        data - The measurement (data) itself.

      • getMeasurementsDao

        public static <Q extends javax.measure.quantity.Quantity> MeasurementsDao<?,​Q> getMeasurementsDao​(DataSeries ds)
        Requests a DAO for a ordinal measurement. If the DAO does not exists it is created and opened automatically (if possible).
        Parameters:
        ds - The data series for which the DAO should be created.
        Returns:
        DAO for ordinal measurements.

      • getMeasuringTypeFromRawMeasurements

        public static MeasuringType getMeasuringTypeFromRawMeasurements​(RawMeasurements rawMeasurements)

      • getMetricDescriptionFromRawMeasurements

        public static org.palladiosimulator.metricspec.MetricDescription getMetricDescriptionFromRawMeasurements​(RawMeasurements rawMeasurements)

      • getTextualBaseMetricDescriptionFromIdentifierMeasurement

        public static org.palladiosimulator.metricspec.TextualBaseMetricDescription getTextualBaseMetricDescriptionFromIdentifierMeasurement​(IdentifierBasedMeasurements idBasedMeasurement)

      • ensureOpenRepository

        public static void ensureOpenRepository​(Repository repo)
                                 throws DataNotAccessibleException
        Opens the data store behind the repository if necessary. Access is only allowed to opened repositories. Repositories may be reopened (and the also reclosed).
        Parameters:
        repo - Repository which should be opened.
        Throws:
        DataNotAccessibleException - if access to the repository fails.

      • ensureClosedRepository

        public static void ensureClosedRepository​(Repository repo)
                                   throws DataNotAccessibleException
        Closes the data store behind the repository if necessary. Access is only allowed to opened repositories. Repositories may be reopened (and the also reclosed).
        Parameters:
        repo - Repository which should be closed.
        Throws:
        DataNotAccessibleException - if access to the repository fails.
