本文整理了Java中hudson.model.Label.parseExpression()方法的一些代码示例，展示了Label.parseExpression()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。Label.parseExpression()方法的具体详情如下：
包路径：hudson.model.Label
类名称：Label
方法名：parseExpression

Label.parseExpression介绍

[英]Parses the expression into a label expression tree. TODO: replace this with a real parser later
[中]将表达式解析为标签表达式树。TODO:稍后用真正的解析器替换它
