Hello,
I want to transform a UML2-model (created with Topcased) to a UML2-model
in ATL.
My source-model use an own created profil vofi_profil.uml (created with
Topcased). The stereotypes are used in classes and in associations.
Now I want to exclude classes with stereotype i.e. <<Komplex>>, and
exclude associations (also compositions) with stereotype i.e. <<Needed>>.
I also need the multiplicies at the association-ends.
Do anybody know a approach to get the necessary information from the model?
Or an example (tutorial) for UML2 to UML2 transformation ?

With superimposition, you have to override all affected rules.
Perhaps it's more efficient in your case to adapt the definition of the
"inElements" attribute helper in UML2Copy.atl.
You cannot redefine helper attributes in a superimposed module,
unfortunately. I've tried it briefly, but it doesn't seem to work.
Perhaps we'll be able to fix this in the future ;-)

Hello everybody,
I use atl Compiler 2006 Plug-in! At the Eclipse "Run dialog", I just had
Regular VM(with debugger) in my drop-down list, so I think both
transformations are compiled by the same compiler.
I specified one metamodel UML2: uri:http://www.eclipse.org/uml2/2.1.0/UML,
in both transformations I use this metamodel.
If I use the the Superimpose mechanism, my transformation will not go far!
/Test/transformations/Buildtime_Projekt_Einfach.atl executed in 0.282 s
(including model loading and saving).
and that's it! :-(
I superimpose the following snippet of code on top of Copy2Model.atl:
module SuperimposeEinfach; -- Module Template
create OUT : UML2 from IN : UML2;
helper context UML2!Element def : hasStereotype(s : String) : Boolean =
if self.getAppliedStereotypes()->select(e | e.name = s)->notEmpty() then
true
else
false
endif;
helper def : inElements : Set(UML2!"ecore::EObject") =
UML2!"ecore::EObject"->allInstancesFrom('IN') ;
rule Class {
from s : UML2!"uml::Class" (
if thisModule.inElements->includes(s) and not
s.hasStereotype('Buildtime-Project-Complex') then
s->oclIsTypeOf(UML2!"uml::Class")
else false endif)
to t : UML2!"uml::Class" mapsTo s (
name <- s.name,
visibility <- s.visibility,
.
. ... the same like in Copy2Model.atl
.
ownedReception <- s.ownedReception)
}
At the Eclipse "Run dialog ..." I append my own created
profile.uml"(Topcased),
enabled inter-models references and continue execution after errors in Run
mode.
---> @Dennis:
your idea, to modify the inElements helper is interesting, could you give
my a snippet code?
I appreciate your help!
Best Regards,
Mani

Even if you're using the latest ATL, the default compiler is still set
to "atl2004" (don't know why). If you want to use the new (faster)
compiler, you have to add the following line at the top of your
transformation module:

I don't have any "Copy2Model.atl". I used "UML2Copy.atl" instead. When I
superimpose your transformation, I get the following error:
SEVERE: Pattern not equal for execution environment and module in main
(getasm != load 0 @ 0)

That means I need to add the "-- @atlcompiler atl2006" line to
SuperimposeEinfach.atl. After I did that, the transformation works.

To do this, you need the latest ATL from CVS, or download ATL from the
following update site:
http://ssel.vub.ac.be/tools/atl/update/
An example transformation that superimposes a new "inElements" on top of
UML2Copy.atl can be found here:
http://ssel.vub.ac.be/viewvc/UML2CaseStudies/uml2cs-transfor mations/UML2FilteredCopy.atl?revision=7373&view=markup
It copies only instances of uml::Package. You'll probably need a more
elaborate OCL statement to exclude all stereotyped classes and all
elements directly or indirectly owned by those classes.

You're welcome ;-)

Hmm, then how do you know you get errors? What kind of errors are they?

Helpers that already exist in the base ATL module don't need to be
specified again. In your case, you can just use the "inElements" from
UML2Copy.atl inside your own transformation module.

Well, that would be to re-define "inElements" in your own
transformation. That requires the latest ATL from CVS, as indicated in
my previous post.
