Methods Documentation

add_extra_arguments(parser)

Add some extra argument to commande line parsing.

If you have to add some, you have to override this method.

Parameters:parser – an ArgumentParser object (with default options added).

get_command(filepath)

init()

Method called after CLI parsing but before processing any files.

process(xaf)

Process one file.

Process one XattrFile. You have to override this method (unless your class inherits from BatchStep, see batch_process() in that case).

The file is moved into a temporary directory before the call with an unique filename. Extended attributes are copied to it. So you can do what you want with it.

If the method returns True:

• we considerer that the processing is ok
• the file is delete if necessary

If the method doesn’t return True:

• we considerer that the processing is not ok (a warning message is

  logged).

• the file is given to the choosen failure policy.

Parameters:xaf – XattrFile object. Returns:processing status (True: ok, False: not ok) Return type:boolean
