actifsource

Hello,

I've two questions:
In our master degree project, we compare some MDA-Tools and we want to create an example for each tool.
In my model, I have an "Application"-class, which can have multiple "Components". These components could be a "Button", a "TextField", a "Label" or something else ("Components" is the superclass of these).
Is it possible to have access to the Button, Textfield etc. in my Template Editor. So that I could write:

//selector: Application.component
if (component==Button)
//do something for Button
if (component==TextField)
//do something for TextField
if (component==Label)
//do something for Label

The if-Statements should not be in my sourcecode.
At the moment I say that the "Application"-class can have Buttons, can have TextField, can have Labels. So I have lots of relations in my class diagram. And in my Template I wrote:
//selector Application.button
do something for Button
//selector Application.textField
do something for TextField
//selector Application.label
do something for Label

The second way is a little bit complicated. Every time, when I create a new subclass, I need to update my class diagram. So I must say the "Application"-class can have can have TextField, can have Labels and now also "Containers".

I write also my second question here: Is ActifSource based on Eclipse Modeling Project (EMF) or do you use Eclipse only to show the GUI of your program? I couldn't find some information about that.
Many Thanks

Hello aDiet,

When Component is the super-class of Button, TextField etc in the model, then you can use a filtering cast in the selector in the template.
So, you have a context with selector "Application.component" and then for each type you make a nested context which have the selectors

• Component:Button
• Component:TextField
• etc

The important thing is the colon, it is used for casting. Like this, the sub-contexts are executed only for those Components which are of the actual sub-type. Hope this answers your first question.

We use part of the EMF (the Draw2d and GEF) for our editors but not EMF. However, we support import of ecore meta-models to actifsource and exporting actifsource to ecore. Further, there is project scheduled which allows to use the actifsource template editor for EMF models.
