Hi All,
I have created a UML profile for a specific domain. In this profile there
are lots of OCL constraints for "well-formedness" and domain model. I want
to be able to validate my "UML diagrams" which "applied my profile".
I searched for a while and i think the way to my solution passes through
EMF Validation framework. For UML and Ecore models there is a validate
option on objects. I want to register my checker to this validator. First,
default checkers validates then my validator takes control? Is this
possible?
I have read "Recipe: How To use the Eclipse Validation Framework with OCL
constraints defined in a separate file". I have created a "genmodel" from
my UML Profile file. By using this genmodel, i generated codes for
plug-in. I generated all 4 projects (xxx, xxx.editor, xxx.edit,
xxx.tests). I realised that after generation there is no seperated OCL
files. All OCL constraints were being checked in xxxImpl objects. This
code validations use OCL framework and validates from there. In this
recipe there is seperated OCL files so i can not apply this receipe for my
problem.
When i directly Run my plug-ins, i saw that there is a New Emf Model
generation for my profile, this is not what i want. I told above what i
want, shortly i want to register my validator to default UMl model
validator.

Hi, Cagdas,
The MDT OCL implementation supports the evaluation of OCL constraints
that are defined in the context of a Stereotype on the model Elements to
which the stereotype is applied. See how this works in the
org.eclipse.ocl.uml.tests.ProfilesTest JUnit test class.
As far as extending the validation action in your editor is concerned,
this is something that you would probably need to do in the
ValidateAction class that is generated in your editor plug-in. You may
find some useful ideas in the EMF Validation Framework examples
(installed from the "EMF Validation Framework Plug-ins" category in the
"New -> Example..." wizard). The "General" example illustrates the
implementation of a Validate action that invokes the
ModelValidationService; the "Adapter" example demonstrates how to bridge
the validation service with your model's generated EValidator; the "OCL"
example demonstrates a couple of different ways to use OCL to define
constraints. For your purpose, an approach like the dynamic OCL
constraint provider example would probably be best, except that instead
of finding constraints in *.ocl files, it would find them in your profiles.
HTH,
Christian
