Detailed Description

Virtual base class for message filters.

A message filter is fed with all messages passing through a MessageSession. It can modify the XML/XMPP structure and/or the message content at will. Messages arriving from the server as well as messages sent to the server can be altered.

Messages to be sent out are presented to the filter via the decorate() function, incoming messages can be filtered in the – filter() method.
