[Acceleo] UML 2 Java - Non basic types + Magicdraw [message #636824]

Hi all,

I´m trying to adapt the Uml2Java example to work with reference types like java.util.Date.

First I tried to use Papyrus (0.7) but it seems it doesn´t have a way to include a profile with non-basic Java types.

So I went to Magicdraw 16, integrated with eclipse. I exported my model as an EMF XMI and ran my acceleo generator. The problem is the generator also generated all classes from the internal profiles of my model.

I need to generate a real world application with all common Java types (or richer UML types, like Date). How can I accomplish that?
Is there a way to do that using Papyrus? or, if not, using MagicDraw?

TIA,
R.

Hi Rodrigo,

Acceleo generates code for what you ask him to. If you feed him an UML
model with three classes "Book", "Media" and "Video" and two data types
"Date" and "String", your generator will either generate three classes
(one for each Class), two classes (oen for each data type), five classes
(one for each model element) ... or even a hundred classes if you decide
to loop and make files for each character in the names and attributes of
your model.

It is up to you to define the generation modules that go with what you'd
like generated.

The modeler itself really has no importance : as long as it suits your
need and can properly export the models to an EMF-readable format, it
can be used with Acceleo. Sebastien Roy has commented on another thread
(

) on his experience with three modelers.

Hi Laurent,

Thanks for your repply.

Where can I find information about how to set acceleo to not generate
the classes from the profiles inside my MagicDraw file?

I think papyrus won´t be a alternative this time...

Hi Rodrigo,

I don't know how you created your generation modules, neither do I know what your models look like. You should take a look at the Acceleo tutorial or its quick start for information on how to define generation modules, it doesn't take long to grasp the principles. Both are available on the Eclipse Help Center.

Basically, you need to determine what you want _not_ generated if they are "classes from the profiles" I suppose they all have something that set them appart from your own classes : a stereotype, an attribute... You can then tell Acceleo not to generate these classes through a guard on the template that contains the "[file/]" block for Class generation, something like this (to prevent generation of Class which have the "my.stereotype" stereotype) :

[...]

[template public generateClass(class : Class) ? (not class.hasStereotype('my.stereotype'))]
[...]
    [file (class.name + '.java', false)]
[...]
[/template]

[...]

Sorry for the double post, hit "quote" instead of "edit" Razz
