Hello,

I would like to know when a end association isNavigable. On order to
generate an attribute only in the class which is in the navigable end of
the association.

Thank you in advance!!

Hello Javier,

Considering UML.

I have seen different implementations of this so it depends on how your
model is created.

Using e.g. a model created in Papyrus UML or IBM RSM you traverse your
ownedAttributes and checks if association !null.

texttransformation NewTrans(in uml:"http://www.eclipse.org/uml2/2.1.0/UML")
{
uml.Class::main () {
stdout.println("Class Name: " + self.name)
self.ownedAttribute->forEach(p:uml.Property | p.association!=null){
stdout.println("Navigable Association: " + p.name)
stdout.println("Navigable AssociationType: " + p.type.name)
}
}
}

on:
class_0
Class_1 ------------>Class_0

Gives output:
Class Name: Class_0
Class Name: Class_1
Navigable Association: class_0
Navigable AssociationType: Class_0

Hello Gøran,

thanks for your answer. Finally it was a problem of the UML editor that
I use (Topcased). There is a bug and when you tick the 'isNavigable'
option in an association, you can not save the model.

Other question there is more documentation about MOFScript. I can only
find the user manual.

Thank you in advance!!

Hi Javier,

The user manual and the built in help functionality Help->Help Contents->
MOFScript should cover the functionality that is available.
There are also some simple example transformations in the repository folder
of the MOFScript editor plugin.

Since MOFScript handles models based on EMF, when it comes to navigating the
different metamodels e.g. UML, you will have to consult the metamodel
specification.
