Method Detail

• noLeakFileList

  public static java.util.stream.Stream<java.nio.file.Path> noLeakFileList(java.nio.file.Path dir)
                                                                    throws java.io.IOException

  A version of Files.list(Path) that won't leak resources.

  Instead, it immediately consumes the entire listing into a List and calls Collection.stream().

  Parameters:

  dir - the directory to list

  Returns:

  an I/O-resource-free stream of the files in the directory

  Throws:

  java.io.IOException - if an I/O error occurs

• canonicalFileName

  public static java.lang.String canonicalFileName(java.nio.file.Path path)

  Path.getFileName() includes a slash sometimes for some reason. This will get rid of it.

  Parameters:

  path - the path to get the file name for

  Returns:

  the file name of the given path

• tryHardToDeleteDir

  public static void tryHardToDeleteDir(java.nio.file.Path directory)
                                 throws java.io.IOException

  Recursively uses tryHardToDelete(Path) to cleanup directories before deleting them.

  Parameters:

  directory - the directory to delete

  Throws:

  java.io.IOException - if an error occurs trying to delete the directory

• tryHardToDelete

  public static void tryHardToDelete(java.nio.file.Path path)
                              throws java.io.IOException

  Tries to delete a path. If it fails the first time, uses an implementation detail to try and make it possible to delete the path, and then tries again. If that fails, throws an IOException with both errors.

  Parameters:

  path - the path to delete

  Throws:

  java.io.IOException - if the path could not be deleted after multiple attempts

• getOwnerOnlyFileAttributes

  public static java.nio.file.attribute.FileAttribute<?>[] getOwnerOnlyFileAttributes(AttributeTarget attributeTarget)

  Get a set of file attributes for file creation with owner-only access, if possible.

  On POSIX, this returns o+rw (and o+x if directory), on Windows it returns nothing.

  Returns:

  the owner-only file attributes
