Class IBB

source code

IBB used to transfer small-sized data chunk over estabilished xmpp connection. Data is split into small blocks (by default 3000 bytes each), encoded as base 64 and sent to another entity that compiles these blocks back into the data chunk. This is very inefficiend but should work under any circumstances. Note that using IBB normally should be the last resort.

Method Details [hide private]

__init__(self)
(Constructor)

source code 

Initialise internal variables.

Overrides: client.PlugIn.__init__

plugin(self, owner)

source code 

Register handlers for receiving incoming datastreams. Used internally.

IqHandler(self, conn, stanza)

source code 

Handles streams state change. Used internally.

StreamOpenHandler(self, conn, stanza)

source code 

Handles opening of new incoming stream. Used internally.

OpenStream(self, sid, to, fp, blocksize=3000)

source code 

Start new stream. You should provide stream id 'sid', the endpoind jid 'to', the file object containing info for send 'fp'. Also the desired blocksize can be specified. Take into account that recommended stanza size is 4k and IBB uses base64 encoding that increases size of data by 1/3.

SendHandler(self, conn)

source code 

Send next portion of data if it is time to do it. Used internally.

ReceiveHandler(self, conn, stanza)

source code 

Receive next portion of incoming datastream and store it write it to temporary file. Used internally.

StreamCloseHandler(self, conn, stanza)

source code 

Handle stream closure due to all data transmitted. Raise xmpppy event specifying successfull data receive.

StreamBrokenHandler(self, conn, stanza)

source code 

Handle stream closure due to all some error while receiving data. Raise xmpppy event specifying unsuccessfull data receive.

StreamOpenReplyHandler(self, conn, stanza)

source code 

Handle remote side reply about is it agree or not to receive our datastream. Used internally. Raises xmpppy event specfiying if the data transfer is agreed upon.
