本文整理了Java中org.apache.lucene.search.Sort.equals()方法的一些代码示例，展示了Sort.equals()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。Sort.equals()方法的具体详情如下：
包路径：org.apache.lucene.search.Sort
类名称：Sort
方法名：equals

Sort.equals介绍

[英]Returns true if o is equal to this.
[中]如果o等于此值，则返回true。
