Method Detail

listfiles

public static List<File> listfiles(File directory,
                                   FileFilter filter,
                                   boolean recursive)

List all files and sub directories of the specified directory, according to the specified filter. If the recursive flag is true, these sub directories are also searched recursively.

Parameters:

directory - the base directory to start listing in

filter - the FileFilter which is applied to each file and directory during the retrial

recursive - if true, iterate all sub directories as well

Returns:

a list of all the files and directories found, or and empty list if directory did not exists, or there was an IO error.

listfiles

public static List<File> listfiles(File directory,
                                   FilenameFilter filter,
                                   boolean recursive)

List all files and sub directories of the specified directory, according to the specified filter. If the recursive flag is true, these sub directories are also searched recursively.

Parameters:

directory - the base directory to start listing in

filter - the FilenameFilter which is applied to each file and directory during the retrial

recursive - if true, iterate all sub directories as well

Returns:

a list of all the files and directories found.

listfilesRecursive

public static List<File> listfilesRecursive(File directory)

List all files and sub directories of the specified directory recursively.

Parameters:

directory - the base directory to start listing in

Returns:

a list of all the files and directories found.

listDirectories

public static List<File> listDirectories(File directory,
                                         boolean recursive)

List all sub directories of the specified directory. If the recursive flag is true, these sub directories are also searched recursively.

Parameters:

directory - the base directory to start listing in

recursive - if true, iterate all sub directories as well

Returns:

a list of all directories found.

printFiles

public static void printFiles(File directory,
                              FileFilter filter,
                              boolean recursive)
