add_child(child, update=False)[source]

get_children(start=0, request_count=0)[source]

called by the CDS and the MediaServer web should return

  • a list of its childs[start:end]
  • or a Deferred

if end == 0, the request is for all childs after start - childs[start:]

get_child_count()[source]

called by the CDS should return

  • the number of its childs - len(childs)
  • or a Deferred
get_id()[source]
get_update_id()[source]
get_path()[source]

called by the MediaServer web should return

  • the filepath where to find the media file that this item does refer to
get_name()[source]

called by the MediaServer web should return

  • the name of the item, it is always expected to be in unicode
get_parent()[source]
get_item()[source]

called by the CDS and the MediaServer web should return

  • an UPnP ContentDirectoryServer DIDLLite object
  • or a Deferred

len()[source]
get_by_id(id)[source]

called by the CDS or the MediaServer web

id is the id property of our DIDLLite item

if this MediaServer implements containers, that can share their content, like ‘all tracks’, ‘album’ and ‘album_of_artist’ - they all have the same track item as content - then the id may be passed by the CDS like this:

‘id@container’ or ‘id@container@container@container…’

therefore a

if isinstance(id, basestring):
id = id.split(‘@’,1) id = id[0]

may be appropriate as the first thing to do when entering this method

should return

  • None when no matching item for that id is found,
  • a BackendItem,
  • or a Deferred
getnextID()[source]
upnp_init()[source]

This method gets called after the device is fired, here all initializations of service related state variables should happen, as the services aren’t available before that point.
