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

BitSet.nextSetBit介绍

[英]Returns the index of the first set bit starting at the index specified. DocIdSetIterator#NO_MORE_DOCS is returned if there are no more set bits.
[中]返回从指定索引开始的第一个集合位的索引。DocIdSetIterator#如果没有更多的设置位，则不会返回更多的文档。
