本文整理了Java中it.geosolutions.jaiext.range.RangeFactory类的一些代码示例，展示了RangeFactory类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。RangeFactory类的具体详情如下：
包路径：it.geosolutions.jaiext.range.RangeFactory
类名称：RangeFactory

RangeFactory介绍

[英]This class is a factory class which creates a Range object for the specific data type. This Range can have 2 bounds or be a single-point range. If the 2 bound values are equal and almost one of them is included, then a single-point range is created, else an exception is thrown. If the minimum bound value is bigger than the maximum value, then the 2 numbers are inverted at the Range creation time.
[中]这个类是一个工厂类，它为特定的数据类型创建一个范围对象。该范围可以有两个边界，也可以是单点范围。如果两个边界值相等，并且几乎包含其中一个，则会创建一个单点范围，否则会引发异常。如果最小界限值大于最大值，则在创建范围时，这两个数字会反转。

代码示例

private Range[] handleMosaicThresholds(double[][] thresholds, int srcNum) {
  Range[] nodata = new Range[srcNum];
  int minSrcNum = Math.min(srcNum, thresholds.length);
  for (int i = 0; i < minSrcNum; i++) {
    double maxValue = Double.NEGATIVE_INFINITY;
    int numBands = thresholds[i].length;
    for (int b = 0; b < numBands; b++) {
      double bandValue = thresholds[i][b];
      if (bandValue > maxValue) {
        maxValue = bandValue;
      }
    }
    nodata[i] = RangeFactory.create(Double.NEGATIVE_INFINITY, true, maxValue, false);
  }
  if (minSrcNum < srcNum) {

      nodata[i] = nodata[0];
