本文整理了Java中de.matrixweb.vfs.VFS类的一些代码示例，展示了VFS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。VFS类的具体详情如下：
包路径：de.matrixweb.vfs.VFS
类名称：VFS

VFS介绍

[英]This implements a file system abstraction which is able to mount native Files as read-only parts into the VFS. The native files are never overwritten. To create a native filesystem from the virtual use #exportFS(File), to import a native filesystem use #importFS(File).
[中]这实现了一个文件系统抽象，它能够将本机文件作为只读部分装载到VFS中。本机文件永远不会被覆盖。要从虚拟使用#exportFS（文件）创建本机文件系统，要导入本机文件系统，请使用#importFS（文件）。
