Required. :param title_type: the type attribute for the title element. One of ``'html'``, ``'text'`` or ``'xhtml'``. :param url: the url for the feed (not the url *of* the feed) :param id: a globally unique id for the feed. Must be an URI. If not present the `feed_url` is used, but one of both is required. :param updated: the time the feed was modified the last time. Must be a :class:`datetime.datetime` object. If not present the latest entry's `updated` is used. :param feed_url: the URL to the feed. Should be the URL that was requested. :param author: the author of the feed. Must be either a string (the name) or a dict with name (required) and uri or email (both optional). Can be a list of (may be mixed, too) strings and dicts, too, if there are multiple authors. Required if not every entry has an author element. :param icon: an icon for the feed. :param logo: a logo for the feed. :param rights: copyright information for the feed. :param rights_type: the type attribute for the rights element. One of ``'html'``, ``'text'`` or ``'xhtml'``. Default is ``'text'``. :param subtitle: a short description of the feed. :param subtitle_type: the type attribute for the subtitle element. One of ``'text'``, ``'html'``, ``'text'`` or ``'xhtml'``. Default is ``'text'``. :param links: additional links. Must be a list of dictionaries with href (required) and rel, type, hreflang, title, length (all optional) :param generator: the software that generated this feed. This must be a tuple in the form ``(name, url, version)``. If you don't want to specify one of them, set the item to `None`. :param entries: a list with the entries for the feed. Entries can also be added later with :meth:`add`. For more information on the elements see http://www.atomenabled.org/developers/syndication/ Everywhere where a list is demanded, any iterable can be used. t Werkzeugc K s= | | _ | j d d � | _ | j d � | _ | j d | j � | _ | j d | j � | _ | j d � | _ | j d d � | _ | j d � | _ | j d � | _ | j d � | _ | j d � | _ | j d � | _ | j d d � | _ | j d � | _ | j d k r&| j | _ n | j d g � | _ | rMt | � pPg | _ t | j d � s�t | j t t f � r�| j g | _ n xC t | j � D]2 \ } } t | t � s�i | d 6| j | <q�q�W| j s�t d � � n | j s t d � � n x, | j D]! } d | k rt d � � qqWd S( Nt title_typet textt urlt feed_urlt idt updatedt authort icont logot rightst rights_typet subtitlet subtitle_typet generatort linkst __iter__R s title is requireds id is requireds# author must contain at least a name( ( t titlet getR R R R R R R R R R R R R t Nonet default_generatorR t listt entriest hasattrt isinstanceR t dictt enumeratet ValueErrort TypeError( t selfR R% t kwargst iR ( ( sD /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/atom.pyt __init__d s> c O sm t | � d k rC | rC t | d t � rC | j j | d � n& | j | d <| j j t | | � � d S( s� Add a new entry to the feed.
