public static java.io.File getNewFileForWriting(java.lang.String path,
boolean can_erase)
path - The path to which the file is to be saved.can_erase - Whether or not the file should be automatically
overwritten if it already exists.
public static java.io.DataOutputStream getDataOutputStream(java.io.File file)
throws java.io.FileNotFoundException
file - The File that will be written to.
java.io.FileNotFoundException - This exception is thrown if the
given file cannot be found.
public static boolean validateFile(java.io.File file,
boolean need_read,
boolean need_write)
throws java.lang.Exception
file - The file to test.need_read - If this is set to true, then an exception is
sent if the file cannot be read from.need_write - If this is set to true, then an exception is
sent if the file cannot be written to.
java.lang.Exception - An informative exception is thrown if there is
a problem with the file.
public static java.io.File[] getAllFilesInDirectory(java.io.File directory,
boolean explore_subdirectories,
java.io.FileFilter filter,
java.util.Vector<java.io.File> results)
directory - The directory to explore.explore_subdirectories - Whether or not the subdirectories of
directory should be explored.filter - A filter controlling what files are
elligible to be returned. A value of
null means all files found will be
returned.results - Used internally for recursive calls.
Pass null when calling this method
externally.
public static boolean createEmptyDirectory(java.lang.String path)
If a deletion fails, then the method stops attempting to delete and returns false.
path - The path at which a directory is to be created.
public static boolean deleteDirectoryRecursively(java.io.File directory)
If a deletion fails, then the method stops attempting to delete and returns false.
directory - The directory to delete.
public static void copyFile(java.lang.String original,
java.lang.String destination)
throws java.lang.Exception
original - The name of the file to be copied.destination - The name of the file to be copied to.
java.lang.Exception - An exception is thrown if a problem occurs
during copying.
