本文整理了Java中org.mozilla.javascript.ast.WhileLoop类的一些代码示例，展示了WhileLoop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。WhileLoop类的具体详情如下：
包路径：org.mozilla.javascript.ast.WhileLoop
类名称：WhileLoop

WhileLoop介绍

[英]While statement. Node type is Token#WHILE.

WhileStatement: 
while ( Expression ) Statement

[中]While声明。节点类型为令牌#WHILE。

WhileStatement: 
while ( Expression ) Statement
