本文整理了Java中antlr.collections.impl.BitSet类的一些代码示例，展示了BitSet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。BitSet类的具体详情如下：
包路径：antlr.collections.impl.BitSet
类名称：BitSet

BitSet介绍

[英]A BitSet to replace java.util.BitSet. Primary differences are that most set operators return new sets as opposed to oring and anding "in place". Further, a number of operations were added. I cannot contain a BitSet because there is no way to access the internal bits (which I need for speed) and, because it is final, I cannot subclass to add functionality. Consider defining set degree. Without access to the bits, I must call a method n times to test the ith bit...ack! Also seems like or() from util is wrong when size of incoming set is bigger than this.bits.length.
[中]替换java的位集。util。比特集。主要区别在于大多数集合运算符返回新集合，而不是“就地”进行oring和anding。此外，还增加了一些操作。我不能包含位集，因为无法访问内部位（这是我需要的速度），并且因为它是最终的，所以我不能子类化以添加功能。考虑定义集合度。在无法访问位的情况下，我必须调用一个方法n次来测试第I位。。。啊！当传入集的大小大于此值时，似乎util中的or（）是错误的。位。长
