SysML & ACCELEO [message #1007255]

I am defining a M2T transformation through Acceleo from an input SysML model defined via papyrus.
I am having some problem while trying to retrieve SysML stereotypes. For the sake of simplicity I just provide a simplified version of the whole transformation.

[module generate('http://www.eclipse.org/papyrus/0.7.0/SysML','http://www.eclipse.org/uml2/3.0.0/UML')]

[template public generateElement(model : Model)  post(trim())]
[comment @main/]
[file ('test.txt',false,'UTF-8')]
[for (c:Block|model.member->selectByType(Block))]
#[c.name/]#
[/for]
[for (c:Class|model.member->selectByType(Class))]
[c.name/] [c.oclIsKindOf(Block)/] [c.oclAsType(Block).base_Class.name/] [c.getAppliedStereotype('SysML::Blocks::Block')->notEmpty()/]
[/for]
[/file]
[/template]

The only output I get for a test model containing just one Block named Block1 is

Block1 false invalid true

which means the Block is not recognized to be an instance of the Block meta-class (see the first for)
it is instead recognized as a stereotyped class.

However I do remember the first for worked in previos Papyrus/Acceleo versions.
Am I doing something wrong?

Hello Andrea,

From the Ecore point of view, a Block simply contains a reference to its base Element (base_Class). There is absolutely no inheritance relationship, it is a reference. And the UML Element contains a few methods to retrieve the applied stereotypes.

Papyrus and UML do not provide any further support. So, basically:

- A Block is not a Class
- A Class cannot be cast to a Block

You can still retrieve the Block object with "c.getStereotypeApplication('SysML::Blocks::Block')"

The same goes for all Stereotypes in all profiles.

If Acceleo provides (or used to provide, or is supposed to...) a specific support for UML Profiles, you will probably find more information directly on their forum.

Regards,
Camille

Andrea,

The actual operation is Element.getStereotypeApplication(Stereotype), which means you'll probably need to write something like that:

c.getStereotypeApplication(c.getAppliedStereotype('SysML::Blocks::Block'))
