How to find out that a message is delayed [message #921564]

Hello everybody,

I have this toy sequence diagram with one delayed message.
I was looking at the corresponding model and the API and it seems
that there is no way, just looking at the model, to understand that
the message is actually delayed and not an horizontal one

Anyone can help?
Thanks

Hi

A partial answer to both your queries.

I know just about nothing about the details of these diagrams, so when I
saw UML 2.5 simplification team discussion on them I took little notice;
however my limited recollection is that the rewriting associated with
the simplification highlighted a number of limitations. You might want
to take a look at http://www.omg.org/cgi-bin/doc?ad/12-08-01 and see if
it helps. (I'm not sure if non-OMG members have access yet - you'll soon
find out.)

Regards

Note the attribute messageSort="asynchCall":

<message xmi:id="..." name="Message" messageSort="asynchCall" receiveEvent="..." sendEvent="..." signature="..."/>

From the spec (section 14.3.22):

Quote:

MessageSort is an enumeration of the following values:
• synchCall - The message was generated by a synchronous call to an operation.
• asynchCall - The message was generated by an asynchronous call to an operation (i.e., a CallAction with
"isSynchronous = false").
• asynchSignal - The message was generated by an asynchronous send action.
• createMessage - The message designating the creation of another lifeline object.
• deleteMessage - The message designating the termination of another lifeline.
• reply - The message is a reply message to an operation call.
