Hello,
I would like to extends my meta-model with constraints AND new Operation.
I've chosen OCL language.
I have some trouble to compile OCL expressions.
I want to edit an ocl file like this :
package test
context TestClass def:
test1(t:String): String =
'coucou1'.concat(t)
def:
test2(t:String): String =
'coucou2'.concat(t)
endpackage
I've tried to compile these definition. the Parser send me an error :
misplace construct. I've rewritten the OCL with only one definition :
package test
context TestClass def:
test1(t:String): String =
'coucou'.concat(t)
endpackage
The parser compile this expression with success. And I can invoke test2
operation later, GREAT!
PROBLEM :
I would like to define and compile some OCL constraints or operation (inv
or def) from files. And call these operations or constraints from other
files or String like this
IOCLHelper helper = HelperUtil.createOCLHelper();
EObject context = (EObject)resource.getContents().get(0);
helper.setContext(TestPackage.eINSTANCE.getTestClass());
OCLExpression exp;
// where exp is the compilation of the OCL file with constraints and
operation
exp = ExpressionsFactory.eINSTANCE.createOCLExpression(expressionS tring);
System.out.println(helper.evaluate(context, "self.test1('toto')"));
System.out.println(helper.evaluate(context, "self.test2('toto')"));
** First I've look at the grammar in your OCL plugin (OCLLPGParser.g
:lpg grammar) and I think that this grammar block me (extended bnf
:notation):
package -> 'package' pathName context+ 'endpackage'
| context*
context -> classifierContext
| operationContext
| propertyContext
classifierContext -> context pathName invOrDef
....
* I would need this :
classifierContext -> context pathName invOrDef+
** Secondly I've tried to do this in another way, I've rewritten the code :
package test
context TestClass def:
test1(t:String): String =
'coucou1'.concat(t)
context TestClass def:
test2(t:String): String =
'coucou2'.concat(t)
endpackage
The parser accept this code but there's an exception thrown that tell me
that 'self' (context) can't be redefined.
The only solution that I saw is to re-run the parser with each new 'def'
or 'inv:'. I don't like this solution.
Please, Does anybody know how can I find the good way to compile OCL
Expressions?
Sorry for the long mail.
Thanks for any helps
Regards
Laurent

Hi, Laurent,
You raise some good problems. You may want to add yourself to the cc list
of an existing bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=144210
regarding providing a public API for parsing OCL documents. Evidently, the
internal API that you are currently using also has problems.
Could you please raise bugs for:
- the problem in the grammar file of classifier context not replicating
invOrDefCS
- the exception complaining that the 'self' context cannot be redefined
I can't promise fixes in time for the 1.0.1 release, but we'll see.
Thanks,
Christian

hello Christian,
thanks for your answer. I entered bugs in bugzilla:
* grammar restriction
https://bugs.eclipse.org/bugs/show_bug.cgi?id=156656
* 'self' cannot be redefine
https://bugs.eclipse.org/bugs/show_bug.cgi?id=156657
I hope that bugs will have to be resolved in the next version ;-)

Laurent
