Method Detail

deleteDirectory

public static void deleteDirectory(File directory)
                            throws IOException

Copied from the apache commons io project Deletes a directory recursively.

Parameters:

directory - - directory to delete

Throws:

IOException - in case deletion is unsuccessful

IllegalArgumentException - if directory does not exist or is not a directory

isSymlink

public static boolean isSymlink(File file)
                         throws IOException

Copied from the apache commons io project 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.

Note: the current implementation always returns false if the system is detected as Windows using Configuration.isWindows()

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

Parameters:

file - - the file to check

Returns:

true if the file is a Symbolic Link

Throws:

IOException - if an IO error occurs while checking the file

Since:

2.0.0

cleanDirectory

public static void cleanDirectory(File directory)
                           throws IOException

Copied from the apache commons io project Cleans a directory without deleting it.

Parameters:

directory - - directory to clean

Throws:

IOException - in case cleaning is unsuccessful

IllegalArgumentException - if directory does not exist or is not a directory

forceDelete

public static void forceDelete(File file)
                        throws IOException

Copied from the apache commons io project Deletes a file. If file is a directory, delete it and all sub-directories.

The difference between File.delete() and this method are:

• A directory to be deleted does not have to be empty.
• You get exceptions when a file or directory must not be deleted. (java.io.File methods returns a boolean)

Parameters:

file - - file or directory to delete, must not be null

Throws:

NullPointerException - if the directory is null

FileNotFoundException - if the file was not found

IOException - in case deletion is unsuccessful

copyFile

public static void copyFile(File srcFile,
                            File destFile,
                            boolean preserveFileDate)
                     throws IOException

Copied from the apache commons io project Internal copy file method. This caches the original file length, and an IOException will be thrown if the output file length is different from the current input file length. So it may fail if the file changes size. It may also fail with "IllegalArgumentException: Negative size" if the input file is truncated part way through copying the data and the new file size is less than the current position.

Parameters:

srcFile - - the validated source file, must not be null

destFile - - the validated destination file, must not be null

preserveFileDate - whether to preserve the file date

Throws:

IOException - if an error occurs

IOException - if the output file length is not the same as the input file length after the copy completes

IllegalArgumentException - "Negative size" if the file is truncated so that the size is less than the position

copyDirectory

public static void copyDirectory(File srcDir,
                                 File destDir)
                          throws IOException

Throws:

IOException

copyDirectory

public static void copyDirectory(File srcDir,
                                 File destDir,
                                 FileFilter filter,
                                 boolean preserveFileDate,
                                 List<String> exclusionList)
                          throws IOException

Copied from the apache commons io project Internal copy directory method.

Parameters:

srcDir - - the validated source directory, must not be null

destDir - - the validated destination directory, must not be null

filter - - the filter to apply, null means copy all directories and files

preserveFileDate - - whether to preserve the file date

exclusionList - - List of files and directories to exclude from the copy, may be null

Throws:

IOException - if an error occurs
