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

Matcher.pattern介绍

[英]Holds the pattern, that is, the compiled regular expression.
[中]保存模式，即编译后的正则表达式。
