Examples of tachyon.UnderFileSystem.list()

tachyon.UnderFileSystem.list()
Returns an array of strings naming the files and directories in the directory denoted by this abstract pathname.
If this abstract pathname does not denote a directory, then this method returns {@code null}. Otherwise an array of strings is returned, one for each file or directory in the directory. Names denoting the directory itself and the directory's parent directory are not included in the result. Each string is a file name rather than a complete path.
There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order. @param path the path to list. @return An array of strings naming the files and directories in the directory denoted by thisabstract pathname. The array will be empty if the directory is empty. Returns {@code null} if this abstract pathname does not denote a directory, or if an I/O erroroccurs. @throws IOException
