This default implementation just calls #increment in a loop over the input array.

Usage

From source file:com.joliciel.jochre.graphics.ShapeImpl.java

double getBrightnessMeanBySector(String key, SectionBrightnessMeasurementMethod measurementMethod) {
    Map<SectionBrightnessMeasurementMethod, Double> methodToMeanMap = this.brightnessMeanBySectorMap.get(key);
    if (methodToMeanMap == null) {
        methodToMeanMap = new HashMap<Shape.SectionBrightnessMeasurementMethod, Double>();
        this.brightnessMeanBySectorMap.put(key, methodToMeanMap);
    }//from   w  w  w .  j  a v  a 2  s .  c  o  m
    Double brightnessMeanBySectorObj = methodToMeanMap.get(measurementMethod);
    double brightnessMeanBySector = 0.0;
    if (brightnessMeanBySectorObj == null) {
        Mean mean = new Mean();
        Map<SectionBrightnessMeasurementMethod, double[][]> brightnessByMethod = this.brightnessBySectorMap
                .get(key);
