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

BitSet.toLongArray介绍

[英]Returns a new long[] containing a little-endian representation of the bits of this BitSet, suitable for passing to valueOf to reconstruct this BitSet.
[中]返回一个新的long[]，其中包含此位集位的小endian表示形式，适合传递给valueOf以重建此位集。
