| Method Summary | |
| public static boolean | copyFile(File src, File dest)
Copy the src file to the destination. | | public static boolean | copyFile(File src, File dest, boolean overwrite)
Copy the src file to the destination.
Parameters:
src -
Parameters:
dest -
Parameters:
overwrite - If target file already exits, and this parameter istrue, overwrite target file (We do this by first deleting the targetfile before we begin the copy). | | public static boolean | copyFile(File src, File dest, long extent)
| | public static boolean | copyFile(File src, File dest, long extent, boolean overwrite)
Copy up to extent bytes of the source file to the destination
Parameters:
src -
Parameters:
dest -
Parameters:
extent - Maximum number of bytes to copy
Parameters:
overwrite - If target file already exits, and this parameter istrue, overwrite target file (We do this by first deleting the targetfile before we begin the copy). | | public static int | copyFiles(File srcDir, Set srcFile, File dest)
| | public static void | copyFiles(File src, File dest)
Recursively copy all files from one directory to another. | | public static void | copyFiles(File src, FilenameFilter filter, File dest, boolean inSortedOrder, boolean overwrite)
Recursively copy all files from one directory to another.
Parameters:
src - File or directory to copy from.
Parameters:
filter - Filename filter to apply to src. | | public static boolean | deleteDir(File dir)
Deletes all files and subdirectories under dir.
Parameters:
dir - true if all deletions were successful. | | public static File[] | getFilesWithPrefix(File dir, String prefix)
Get a list of all files in directory that have passed prefix.
Parameters:
dir - Dir to look in.
Parameters:
prefix - Basename of files to look for. | | public static FileFilter | getRegexpFileFilter(String regexp)
Get a @link java.io.FileFilter that filters files based on a regular
expression.
Parameters:
regexp - the regular expression the files must match. | | public static String[] | getSortedDirContent(File src, FilenameFilter filter)
Parameters:
src - Directory of files to fetch.
Parameters:
filter - Filter to apply to filenames. | | public static File | isReadable(File f)
Test file exists and is readable. | | public static boolean | isReadableWithExtensionAndMagic(File f, String uncompressedExtension, String magic)
Parameters:
f - File to test. | | public static File | maybeRelative(File context, String path)
Turn path into a File, relative to context (which may be ignored
if path is absolute). | | public static String | readFileAsString(File file)

Use for case where files are being added to src. | | protected static void | workaroundCopyFile(File src, File dest)
|

| deleteDir | | public static boolean deleteDir(File dir)(Code) | | Deletes all files and subdirectories under dir.
Parameters:
dir - true if all deletions were successful. If a deletion fails, themethod stops attempting to delete and returns false. |

prefix - Basename of files to look for. Compare is case insensitive. List of files in dir that start w/ passed basename. |
| getRegexpFileFilter | | public static FileFilter getRegexpFileFilter(String regexp)(Code) | | Get a @link java.io.FileFilter that filters files based on a regular
expression.
Parameters:
regexp - the regular expression the files must match. the newly created filter. |

src - Directory of files to fetch.
Parameters:
filter - Filter to apply to filenames. Files in directory sorted. |
| isReadable | | public static File isReadable(File f) throws IOException(Code) | | Test file exists and is readable.
Parameters:
f - File to test.
exception:
IOException - If file does not exist or is not unreadable. |
