方法详细资料

hasFreeSpace

public static boolean hasFreeSpace(File path,
                                   long size)

Checks if the request number of bytes of free disk space are available under the given path.

参数:

path - Directory to check

size - Bytes of free space requested

返回:

True iff the free space in the specified path meets or exceeds the requested space

isHidden

public static boolean isHidden(File file)

isNotSymlink

public static boolean isNotSymlink(File file)
                            throws IOException

Determines whether the specified file is a Symbolic Link rather than an actual file.

Will not return true if there is a Symbolic Link anywhere in the path, only if the specific file is.

When using jdk1.7, this method delegates to boolean java.nio.file.Files.isSymbolicLink(Path path)

Note: the current implementation always returns false if running on jdk1.6

For code that runs on Java 1.7 or later, use the following method instead:
boolean java.nio.file.Files.isSymbolicLink(Path path)

参数:

file - the file to check

返回:

true if the file is a Symbolic Link

抛出:

IOException - if an IO error occurs while checking the file

isSymlink

public static boolean isSymlink(File file)
                         throws IOException

抛出:

IOException
