本文整理了Java中javax.persistence.criteria.Path.getParentPath()方法的一些代码示例，展示了Path.getParentPath()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。Path.getParentPath()方法的具体详情如下：
包路径：javax.persistence.criteria.Path
类名称：Path
方法名：getParentPath

Path.getParentPath介绍

[英]Return the parent "node" in the path or null if no parent.
[中]返回路径中的父节点，如果没有父节点，则返回null。
