UML Profiles

[caitken]

I'm developing an MDG Technology and want to be able to limit the relationships allowed between elements of the profile to only those defined with the stereotypes in the profile. Any pointers on how to achieve this would be appreciated.

You can not really limit them. The quick linker just presents the useful subset of connectors. But via the standard toolboxes one can create any UML-valid connector. If you really want to do a check you need to intercept the creation via the OnPreNewConnector event.

Thanks. I noticed that the BPMN MDG Technology doesn't allow flows to cross pools - does it use the same call to police this rule? or a different approach?

[qwerty]

Haven't developed that, you need to ask Sparx...

I'm afraid it's done in EA, not the technology

[caitken]

Is there no way that I could implement something similar using Constraints in EA? i.e., a constraint on the stereotype that checks the type of the source and destination?

[KP]

Unfortunately not.

qwerty gave you the answer that you need to write an add-in that implements the EA_OnPreNewConnector broadcast event.

[caitken]

Are there any plans to add relational integrity checking to the core product?

[caitken]

I'll take that as a - no.

I'll take that as a - no.

Or you could take it as an "I don't make those decisions". It's certainly a feature I would like to see in EA.
