3.1.7.2.1 Received Message

  • Article

The Received Message event is signaled when a TCP message arrives on the TIP port. When this event is signaled, the TIP transaction manager facet MUST perform the following actions:

  • If the value of the Allow Non-Default Port flag is FALSE and the provided TCP connection did not originate from port 3372, terminate the connection and terminate the processing of this event.

  • Call the GetTipConnection operation (section 3.1.1.3.1) with the TCP connection as an input parameter. This returns a TIP connection object (section 3.1.1.2) whose data fields include the following:

    • Transport Connection: The provided TCP connection.

  • Parse the message data into separate TIP commands according to the ABNF rules as specified in section 2.2. To support Pipelining, the incoming message is parsed into separate TIP commands.

  • If this parsing is not successful, signal the Invalid TIP Command event (section 3.1.7.1) and terminate the processing of this event.

  • For each of the TIP commands in this message, do the following:

    • Build a TIP command object from the parsed TIP command name, parameters, and the TIP connection object.

    • The TIP command object is now ready to be processed as an incoming message event.
