[ATL] UML2 to UM2 transformation [message #63965] Sat, 13 October 2007 07:44 Go to next message

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 ?

Hello Mani,

Have you looked at the examples here:
http://www.eclipse.org/m2m/atl/atlTransformations/ ?
Especially the UML2MOF example.

Alfons

Hi,

I advised to use superimposition mechanism
(http://wiki.eclipse.org/ATL_Superimposition).

In a first time you need to have a transformation that made a simple
copy of a UML2 model. You can use the UML2Copy transformation made by
Dennis and available here:
http://ssel.vub.ac.be/viewcvs/viewcvs.py/UML2CaseStudies/uml 2cs-transformations/UML2Copy.atl?rev=7250&view=markup

Then, you need to write a transformation that will do the "exclusion".
For example:
----------------------------------
module UML2Filter;
create OUT : UML2 from IN : UML2, PRO : UML2;

helper context UML2!Element def : hasStereotype(s : String) : Boolean =
if self.getAppliedStereotypes()->select(e | e.name = s)->notEmpty() then
true
else
false
endif;

rule Class {
from
s : UML2!Class (not s.hasStereotype('Komplex'))
to
t : UML2!Class(

)
}
----------------------------------

HTH.

Regards,
Freddy.

Hello,

first of all thank you for your advise!
I tried the superimposition mechanism. Copying the model was succesful,
but the exclusion failed!

I tried the 'exclusion' without Copying the model (UML2Copy.atl) and it
wokrs!

But when I try to Copy the model and superimpose the snippet code on top,
the target model is empty!

I do it like in http://wiki.eclipse.org/ATL_Superimposition !


I work with Eclipse 3.3 and ATL 2.0.0 .

I would be pleased for any advise, thank you in advance!

I don't solve the problem, but I had another question!
I want to exclude all Classes with stereotype 'Komplex' plus all related

Is there a function for that, or had I do that by overriding the rules
(Property, association ...).

Thank you in advance!

If both transformations work, but you cannot combine them with
superimposition, make sure the following things are ok:

- Both transformations are compiled by the same compiler (atl2004 or
atl2006). Check the compiler directive on the first line:
"-- @atlcompiler atl2006"

- The model/metamodel declarations are compatible. If there is a model
named "IN" in both transformations, it must have the same metamodel.

If you still have problems, please post the source code of the
transformation you're trying to superimpose.

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 ;-)

I just dug a bit deeper on this issue. It is definitely a bug, which can
trigger for *any* helper attribute that uses a "select" statement or
similar. Here's the bug report:

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:

-- @atlcompiler atl2006

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.

Hello,

thanks now it works!
I had think about your idea, to overwrite the inElements() helper. I had
do that in my Superimpose.atl (superimpose on UML2Copy.atl).

-- @atlcompiler atl2006
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');


I had run it, but it takes about 30min, and after that I get errors, but
they are don't specified!

Is there an syntactic error, or maybe I cannot overwirte the helper!

Do you know a more efficient idea than mine?

best Regards,
Mani

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.

>
> Do you know a more efficient idea than mine?

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.
