本文整理了Java中com.bigdata.service.geospatial.ZOrderRangeScanUtil类的一些代码示例，展示了ZOrderRangeScanUtil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。ZOrderRangeScanUtil类的具体详情如下：
包路径：com.bigdata.service.geospatial.ZOrderRangeScanUtil
类名称：ZOrderRangeScanUtil
[英]Class providing utility functions for efficient zOrder-based multi-dimensional range scans, such as efficient range checks and functionality for BigMin calculation. The latter follows the logics defined in the BIGMIN decision table as provided in http://www.vision-tools.com/h-tropf/multidimensionalrangequery.pdf, page 76. This class is not thread-safe.
[中]类提供用于高效基于zOrder的多维范围扫描的实用函数，例如有效的范围检查和用于BigMin计算的功能。后者遵循中提供的BIGMIN决策表中定义的逻辑http://www.vision-tools.com/h-tropf/multidimensionalrangequery.pdf，第76页。这个类不是线程安全的。
