本文整理了Java中org.openide.filesystems.FileUtil.isParentOf()方法的一些代码示例，展示了FileUtil.isParentOf()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。FileUtil.isParentOf()方法的具体详情如下：
包路径：org.openide.filesystems.FileUtil
类名称：FileUtil
方法名：isParentOf

FileUtil.isParentOf介绍

[英]Recursively checks whether the file is underneath the folder. It checks whether the file and folder are located on the same filesystem, in such case it checks the parent FileObject of the file recursively until the folder is found or the root of the filesystem is reached.

Warning: this method will return false in the case that folder == fo.
[中]递归检查文件是否位于文件夹下。它检查文件和文件夹是否位于同一文件系统上，在这种情况下，它会递归检查文件的父级FileObject，直到找到文件夹或到达文件系统的根。
警告：如果folder == fo，此方法将返回false。
