Directed Connector

[andreas.morgenstern@iese.fraunhofer.de]

Hi,

I'm currently developing a DSL for Function Networks.

Function Profile.jpg

There, functions have types, may be instantated and exchange data.

.
In the example, I created two types, a Light Controller and Light.
We have two instances of Light, the Front and Back Light.

Since I'm connecting instances of functions, I think I have to use a connector to
connect the ports. However, with the exception of adding an information item (in the figure to the connector to Front Light),
I found no way how to model the direction of the connector.
Is there a way to specify in the profile that a connector is a directed relationship ?
(or as an alternative to change the information flow to use the instances instead of the types)

Hello Andreas Morgenstern,

Connector is not directed and can't be made directed. Also Information flow also connects between types, not instances. Unfortunately there is no way to change it either.
Sorry for the inconvenience.

Hi,

Thanks for your answer. Is there any other directed relationship that can be used for instances?

"Feature" seems to be a generalization of Connector that has directionality. . . Perhaps you could model a new stereotype that generalizes off of connector, then set the allowedrelationships property and source and target properties in its customization to create the type of connector you want?

Also, if you mean to have direction arrows from source to target on your connector, you would have to mess with the icon property in its specification window to set line width and connector end types. That is separate from the stereotype and customizations on the profile diagram stuff.

I believe you could generalize your data flow connector off of the standard 'directed connection' in the sysML profile, no? It wouldn't stop you from then using information flows in the opposite direction, though.
