### __init__(self, jid=None, password=None, server=None, port=5222, auth_methods=`(``'``sasl:DIGEST-MD5``'``)`, tls_settings=None, keepalive=0) (Constructor) | source code
Initialize a Client object. Parameters: `jid` (: pyxmpp.JID) - : user full JID for the connection. `password` (: `unicode`) - : user password. `server` (: `unicode`) - : server to use. If not given then address will be derived form the JID. `port` (: `int`) - : port number to use. If not given then address will be derived form the JID. `auth_methods` (: sequence of `str`) - : sallowed authentication methods. SASL authentication mechanisms in the list should be prefixed with "sasl:" string. `tls_settings` (: pyxmpp.TLSSettings) - : settings for StartTLS -- TLSSettings instance. `keepalive` (: `int`) - : keepalive output interval. 0 to disable.

### __roster_error(self, iq) | source code
Process roster request failure. Parameters: `iq` (: pyxmpp.Iq) - : IQ error stanza received as result of the roster request. Raises: `ClientError`

### __roster_push(self, iq) | source code
Process a "roster push" (change notification) received. Parameters: `iq` (: pyxmpp.Iq) - : IQ result stanza received.

### __roster_result(self, iq) | source code
Process roster request success. Parameters: `iq` (: pyxmpp.Iq) - : IQ result stanza received in reply to the roster request.

### __roster_timeout(self) | source code
Process roster request time out. Raises: `ClientError`

### __session_error(self, iq) | source code
Process session request failure. Parameters: `iq` (: pyxmpp.Iq) - : IQ error stanza received as result of the session request. Raises: `FatalClientError`

### __session_result(self, _unused) | source code
Process session request success. Parameters: `_unused` (: pyxmpp.Iq) - : IQ result stanza received in reply to the session request.

### __session_timeout(self) | source code
Process session request time out. Raises: `FatalClientError`

### __stream_state_change(self, state, arg) | source code
Handle stream state changes. Call apopriate methods of self. Parameters: `state` (: `str`) - : the new state. `arg` - : state change argument.

### _session_started(self) | source code
Called when session is started. Activates objects from `self.interface_provides` by installing their stanza handlers, etc.

### authenticated(self) | source code
Handle "authenticated" event. May be overriden in derived classes. This one does nothing.

### authorized(self) | source code
Handle "authorized" event. May be overriden in derived classes. This one requests an IM session.

### connect(self, register=False) | source code
Connect to the server and set up the stream. Set self.stream and notify self.state_changed when connection succeeds.

### connected(self) | source code
Handle "connected" event. May be overriden in derived classes. This one does nothing.

### disconnected(self) | source code
Handle "disconnected" event. May be overriden in derived classes. This one does nothing.

### get_socket(self) | source code
Get the socket object of the active connection. Returns: `socket.socket` socket used by the stream.

### get_stream(self) | source code
Get the connected stream object. Returns: pyxmpp.ClientStream stream object or `None` if the client is not connected.

### idle(self) | source code
Do some "housekeeping" work like cache expiration or timeout handling. Should be called periodically from the application main loop. May be overriden in derived classes.

### loop(self, timeout=1) | source code
Simple "main loop" for the client. By default just call the `pyxmpp.Stream.loop_iter` method of self.stream, which handles stream input and self.idle for some "housekeeping" work until the stream is closed. This usually will be replaced by something more sophisticated. E.g. handling of other input sources.

### roster_updated(self, item=None) | source code
Handle roster update event. May be overriden in derived classes. This one does nothing. Parameters: `item` (: pyxmpp.RosterItem) - : the roster item changed or `None` if whole roster was received.

### session_started(self) | source code
Handle session started event. May be overriden in derived classes. This one requests the user's roster and sends the initial presence.

### stream_closed(self, stream) | source code
Handle stream closure event. May be overriden in derived classes. This one does nothing. Parameters: `stream` (: pyxmpp.ClientStream) - : the new stream.

### stream_created(self, stream) | source code
Handle stream creation event. May be overriden in derived classes. This one does nothing. Parameters: `stream` (: pyxmpp.ClientStream) - : the new stream.

### stream_error(self, err) | source code
Handle stream error received. May be overriden in derived classes. This one passes an error messages to logging facilities. Parameters: `err` (: pyxmpp.error.StreamErrorNode) - : the error element received.

### stream_state_changed(self, state, arg) | source code
Handle any stream state change. May be overriden in derived classes. This one does nothing. Parameters: `state` (: `str`) - : the new state. `arg` - : state change argument.

Instance Variable Details | [hide private]

### auth_methods : methods allowed for stream authentication. SASL mechanism names should be preceded with "sasl:" prefix. Type: : `list` of `str`

### interface_providers : list of object providing interfaces that could be used by the Client object. Initialized to [`self`] by the constructor if not set earlier. Put objects providing IPresenceHandlersProvider, IMessageHandlersProvider, IIqHandlersProvider or IStanzaHandlersProvider into this list. Type: : `list`
