                                                 LegacyClientStream

Handles Jabber (both XMPP and legacy protocol) client connection stream.

Both client and server side of the connection is supported. This class handles client SASL and legacy authentication, authorisation and XMPP resource binding.

### __init__(self, jid, password=None, server=None, port=5222, auth_methods=`(``'``sasl:DIGEST-MD5``'``,` `'``digest``'``)`, tls_settings=None, keepalive=0, owner=None)
(Constructor)

source code

Initialize a LegacyClientStream object.

Parameters:
  - `jid` (pyxmpp.JID) - local JID.
  - `password` (`unicode`) - user's 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.
  - `owner` - Client, Component or similar object "owning" this stream.
Overrides: xmlextra.StreamHandler.__init__
