This class adds support for 'chat' style protocols - where one side sends a 'command', and the other sends a response (examples would be the common internet protocols - smtp, nntp, ftp, etc..). The handle_read() method looks at the input stream for the current 'terminator' (usually '\r\n' for single-line responses, '\r\n.\r\n' for multi-line output), calling self.found_terminator() on its receipt. for example: Say you build an async nntp client using this class. At the start of the connection, you'll have self.terminator set to '\r\n', in order to process the single-line greeting. Just before issuing a 'LIST' command you'll set it to '\r\n.\r\n'. The output of the LIST command will be accumulated (using your own 'collect_incoming_data' method) up to the terminator, and then control will be returned to you - by calling your self.found_terminator() method. i����N( t deque( t py3kwarning( t filterwarningst catch_warningst async_chatc B s� e Z d Z d Z d Z d d d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z RS( s� This is an abstract class.
