Parameters:   pPathToDelete - file or directory to test true if path is not present or can be removed. public static  void copyDirectory(String pFromDirectoryPath, String pToDirectoryPath)      Copies contents of the from directory (excluding directory itself) to the destination directory (again excluding directory itself). public static  File createTempDir(String pPrefix, String pSuffix)      This utility method is almost the same as File.createTempFile() method, with the only difference is that it creates directory and not a file. public static  void deleteAllDirectoryContents(File pDirectory)      public static  void deleteAllFilesInTheDirectory(File pDirectory)      Deletes all files in the specified directory. public static  void deleteDirectory(File pDirectory)      public static  void deleteDirectoryIfExists(File pDirectory)      Deletes all contents of the specified directory including directory itself. public static  void ensureNewCleanDirectory(String pDirectoryPath)      public static  void ensureNewNoFilesDirectory(String pDirectoryPath)      Makes sure that the directory without files exists and accessible. Cleans up contents of the existing directory if necessary. public static  void ensureThereIsDirectory(String pDirectoryPath)      public static  String getUniqueTempDirectoryAbsolutePath()      public static  String[] listAllChildDirectoriesInDirectory(String pDirectoryAbsolutePath)      public static  String[] listAllDescendantDirectoriesInDirectory(String pDirectoryAbsolutePath)      public static  String[] listAllDirectoriesWithName(String pRootDirectoryAbsolutePath, String pNameToLookFor)      Lists all directories contained in the directory and all subdirectories which have its last name equal to the given one. public static  String[] listAllFilesInDirectory(String pDirectoryAbsolutePath, FileFilter pFilter)      Lists all files contained in the directory and possibly subdirectories, which are satisfying given file filter. public static  String[] listAllFilesInDirectory(String pDirectoryAbsolutePath)      public static  void trimDirectoryTree(String pTreeRootDirectoryPath)      Trims tree of directories excluding specified directory. Method Detail canCreate public static boolean canCreate(File pPathToCreate)(Code) Returns true if specified path can be created. Parameters:   pPathToCreate - file or directory to test true if path is not present and can be created canDelete public static boolean canDelete(File pPathToDelete)(Code) Returns true if specified path can be deleted. Parameters:   pPathToDelete - file or directory to test true if path is not present or can be removed. For directorybeing able to remove means that all it's contents are writeable including subdirectories copyDirectory public static void copyDirectory(String pFromDirectoryPath, String pToDirectoryPath) throws FileNotFoundException, IOException(Code) Copies contents of the from directory (excluding directory itself) to the destination directory (again excluding directory itself). Same files get overwritten createTempDir public static File createTempDir(String pPrefix, String pSuffix) throws IOException(Code) This utility method is almost the same as File.createTempFile() method, with the only difference is that it creates directory and not a file. deleteAllDirectoryContents public static void deleteAllDirectoryContents(File pDirectory) throws IOException(Code) Deletes all contents of the specified directory including subdirectories, but excluding the directory itself deleteAllFilesInTheDirectory public static void deleteAllFilesInTheDirectory(File pDirectory) throws IOException(Code) Deletes all files in the specified directory. This excludes any subdirectories deleteDirectory public static void deleteDirectory(File pDirectory) throws IOException(Code) Deletes all contents of the specified directory including directory itself deleteDirectoryIfExists public static void deleteDirectoryIfExists(File pDirectory) throws IOException(Code) Deletes all contents of the specified directory including directory itself. Does not fail if directory does not exist - just exist gracefully ensureNewCleanDirectory public static void ensureNewCleanDirectory(String pDirectoryPath) throws IOException(Code) Makes sure that the clean directory exists and accessible cleans up contents of the existing directory if necessary ensureNewNoFilesDirectory public static void ensureNewNoFilesDirectory(String pDirectoryPath) throws IOException(Code) Makes sure that the directory without files exists and accessible. Cleans up contents of the existing directory if necessary. This version does not touch any subdirectories. Use ensureNewCleanDirectory() if you wish to ensure that totally clean director exists. ensureThereIsDirectory public static void ensureThereIsDirectory(String pDirectoryPath)(Code) Makes sure that the directory exists and accessible creates directory if necesary getUniqueTempDirectoryAbsolutePath public static String getUniqueTempDirectoryAbsolutePath()(Code) Generates the ful path for the unique temporary directory listAllChildDirectoriesInDirectory public static String[] listAllChildDirectoriesInDirectory(String pDirectoryAbsolutePath) throws FileNotFoundException(Code) Lists all direct child directories contained in the directory array of strings with each element being an absolute path to the child directory of the specified directory listAllDescendantDirectoriesInDirectory public static String[] listAllDescendantDirectoriesInDirectory(String pDirectoryAbsolutePath) throws FileNotFoundException(Code) Lists all descendant directories (on any level) contained in the directory array of strings with each element being an absolute path to the descendant directory of the specified directory listAllDirectoriesWithName public static String[] listAllDirectoriesWithName(String pRootDirectoryAbsolutePath, String pNameToLookFor) throws FileNotFoundException(Code) Lists all directories contained in the directory and all subdirectories which have its last name equal to the given one. List is in no particular order. Search will stop at the first match and not go any deeper. So if there is a directory ......\name\.....\name only to level directory will be returned Parameters:   pRootDirectoryAbsolutePath - the absolute path to the directory to start search from Parameters:   pNameToLookFor - the name to match array of strings with each element being an absolute path to the directory matching the criteria listAllFilesInDirectory public static String[] listAllFilesInDirectory(String pDirectoryAbsolutePath, FileFilter pFilter) throws FileNotFoundException(Code) Lists all files contained in the directory and possibly subdirectories, which are satisfying given file filter. Note that subdirectories will onbly be considered if file filter accepts them array of strings with each element being an absolute path to the file contained in the directory listAllFilesInDirectory public static String[] listAllFilesInDirectory(String pDirectoryAbsolutePath) throws FileNotFoundException(Code) Lists all files contained in the directory and all subdirectories in no particular order array of strings with each element being an absolute path to the file contained in the directory trimDirectoryTree public static void trimDirectoryTree(String pTreeRootDirectoryPath) throws FileNotFoundException, IOException(Code) Trims tree of directories excluding specified directory. Trimming means deleting the directories without any contents.
