Solve the following python programming problem given the following code:
def cli_empty_container(context, path, until_empty = False) : 
    "
    Deletes all objects in the container.

    By default, this will perform one pass at deleting all objects in
    the container.
so if objects revert to previous versions or if new
    objects otherwise arise during the process, the container may not be
    empty once done.

    Set `until_empty` to True if you want multiple passes to keep trying
    to fully empty the container. Note until_empty=True could run
    forever if something else is making new objects faster than they're
    being deleted.

    See :py:mod:`swiftly.cli.delete` for context usage information.

    See :py:class:`CLIDelete` for more information.
