| Summary | 0005786: STF409 question on [Part 1: TTCN-3 Core Language / Section 6.3.4 ] | ||||||||
| Description | The content of section 6.3.4 is not clear. Specific issues: - The given example is incomplete, because the port definitions are missing. - It is not clear what happens when a communications port is defined to process the messages of a given record type as well as its type synonym. | ||||||||

In the example, it is stated (albeit in a comment) that the port can process (i.e. send/receive) both types (contrary to your stated point 2). Since the ports are connected (not mapped, where the situation is a bit more difficult because of encoding/decoding), the sent type must be exactly the same as the type of the template to be received (not just compatible) so that matching occurs on the receive statement. This is what the whole section is about. So, the example is in essence complete. However, the example is still wrong in two respects (in my opinion): - P2.receive(MyRec:?) shall not cause an error, but simply a mismatch (there could be other or default alternatives that receive MyRecAlias) - P2.receive(MyRec:?) -> value x shall also not cause an error, as - again - this is simply a mismatch and thus no assignment shall take place. And even if an assignment would take place, assigning of a value of one type to a variable of a different type is well defined using the weaker type compatibility rules (but since there will be no matching here, this point is moot - however, in a mapped port, this could be valid). |

STF discussion on 30-11-2010: add the port type definition to the example. Also fix Jacob's findings. |
