本文整理了Java中org.geotools.util.Range.isEmpty方法的一些代码示例,展示了Range.isEmpty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。Range.isEmpty方法的具体详情如下:
包路径:org.geotools.util.Range
类名称:Range
方法名:isEmpty

Range.isEmpty介绍

[英]Returns true if this range is empty. A range is empty if the #getMinValue is smaller than the #getMaxValue, or if they are equals while at least one of them is exclusive.
[中]如果此范围为空,则返回true。如果#getMinValue小于#getMaxValue,或者如果它们相等,但至少有一个是独占的,则范围为空。
