Read "Duration Constraint between Messages" from Sequence Diagram in C# script

[ankur]

Hello,

I am designing a Scheduling process using UML Sequence Diagram. I am trying to read "Duration Constraint between Messages" property from Sequence Diagram in C# Object Model. 

I can see that this property can be read out using Transitions Collection (refer Page number 175 of Enterprise Architect Object Model document) in State Diagrams. But I cannot find any possibility to read the property from Sequence Diagram.

I saw in some post that you can add the Constraint Note in the Sequence diagram. But as also suggested by some user, due to large number of elements, the Constraint notes make the diagram very congested and cluttered.

Is there any possibility to read this data using standard Enterprise Architect API variables in C# or any other scripting language ?

Edit: "Duration Constraint between Messages" is available when you right-click a Sequence between two Lifelines in Sequence Diagram and go to Timing Details...

I'm not sure what you mean by "duration constraint between messages". Can you post an example?

The "Duration Constraint Between Messages" are marked in the Red rectangles:

In the connector styleEx property you find

SEQDC=<val>; where <val> Duration Constraint

and others. See p. 58 of my Inside book.

Hello,

Thanks for the responses. I went through the Inside EA book (Connector StyleEx Property section).

Since I am quite new to EA, I would like to know how can I use the Connector StyleEx Property to read the Duration Constraint. A pseudo code or a link directing me to some further explanation will be quite helpful.

Thanks in advance.

Ankur,

The StyleEx is in a key1=Value1;key2=Value2 format.
Do some experimenting and you'll surely figure out what goes where.

It should be sufficient to split the styleEx by ";" and examine the sub-strings. The one starting with "SEQDC" has the duration between the "=" and the ";".

Hello,

I could reach up to this point:

SELECT * FROM t_connector.StyleEx where SEQDC="Duration Constraint"

I know it is not close enough but I can guesstimate that <val> has to be a part of the query. Can someone please correct it ?

Thanks in advance.

Hi Ankur,

I though you were using the object model, and now you want to query the database?

Anyhow, the "SQL" you wrote is not even close. I think you better first get a grasp of the basics of SQL.

Hi Geert,

That was just a logic that I was trying to build from the information you provided. It was more of a pseudocode.

I looked it up in the object model and found out that the Duration Constraint Between Messages is provided in the form of DCBM=<value>
