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

Util.isSymlink介绍

[英]Checks if the given file represents a symlink. Unlike Files#isSymbolicLink(Path), this method also considers NTFS junction points as symbolic links.
[中]检查给定文件是否表示符号链接。与文件#isSymbolicLink（Path）不同，此方法还将NTFS junction points视为符号链接。

   *  Windows Directory Junctions are effectively the same as Linux symlinks to directories.
   *  Unfortunately, the Java 7 NIO2 API function isSymbolicLink does not treat them as such.
   *  It thinks of them as normal directories.  To use the NIO2 API & treat it like a symlink,
   *  you have to go through BasicFileAttributes and do the following check:
   *     isSymbolicLink() || isOther()
   *  The isOther() call will include Windows reparse points, of which a directory junction is.
   *  It also includes includes devices, but reading the attributes of a device with NIO fails
   *  or returns false for isOther(). (i.e. named pipes such as \\.\pipe\JenkinsTestPipe return
   *  false for isOther(), and drives such as \\.\PhysicalDrive0 throw an exception when
   *  calling readAttributes.
