"""Abstract base class for federation servlet classes.
The servlet object should have a PATH attribute which takes the form of a regexp to
match against the request path (excluding the /federation/v1 prefix).
The servlet should also implement one or more of on_GET, on_POST, on_PUT, to match
the appropriate HTTP method. These methods have the signature:
on_<METHOD>(self, origin, content, query, **kwargs)
With arguments:
origin (unicode|None): The authenticated server_name of the calling server,
unless REQUIRE_AUTH is set to False and authentication failed.
content (unicode|None): decoded json body of the request. None if the
request was a GET.
query (dict[bytes, list[bytes]]): Query params from the request. url-decoded
(ie, '+' and '%xx' are decoded) but note that it is *not* utf8-decoded
yet.
**kwargs (dict[unicode, unicode]): the dict mapping keys to path
components as specified in the path match regexp.
Returns:
Deferred[(int, object)|None]: either (response code, response object) to
return a JSON response, or None if the request has already been handled.
Raises:
