EFS.getNullFileSystem介绍

[英]Returns the null file system. The null file system can be used to represent a non-existent or unresolved file system. An example of a null file system is a file system whose location is relative to an undefined variable, or a system whose scheme is unknown.

Basic handle-based queries can be performed on the null file system, but all operations that actually require file system access will fail.
[中]返回空文件系统。空文件系统可用于表示不存在或未解析的文件系统。空文件系统的一个示例是位置相对于未定义变量的文件系统，或者方案未知的系统。
可以在空文件系统上执行基于句柄的基本查询，但所有实际需要访问文件系统的操作都将失败。
