Method Detail

getColor

public static java.awt.Color getColor(ETrafficLightColor color)

Returns the color used for visualizing a traffic light color.

compareAssessments

public static int compareAssessments(Assessment o1,
                                     Assessment o2)

Compares two Assessments returning which is "better" than another one.

Returns:

the value 0 if o1 is equal to o2; a value less than 0 if o1 is worse than o2; and a value greater than 0 if o1 is better than o2.

calculateAndFormatDelta

public static java.lang.String calculateAndFormatDelta(Assessment oldAssessment,
                                                       Assessment newAssessment)

Calculates a delta string for two given assessments. Only colors RED, YELLOW and GREEN.

calculateAndFormatDelta

public static java.lang.String calculateAndFormatDelta(ETrafficLightColor color,
                                                       Assessment oldAssessment,

Calculates a delta string for a given color for two given assessments containing the color frequency delta and the relative delta change.

computeRelativeFrequencyDelta

public static double computeRelativeFrequencyDelta(ETrafficLightColor color,
                                                   Assessment oldAssessment,
                                                   Assessment newAssessment)

Calculate the relative color frequency delta to the given assessments
