Hi,
Could someone tell me how to get the comments in a document ocl (OCLInput)?

package Example
 
context School
-- commentary1
inv one_enrollment_for_student :
self.schoolOf->forAll( x: Student | x.enr1->intersection(self.enr2)->size() = 1 )

context School
-- commentary2
inv unique_id:
self.enr2->isUnique(x: Enrollment | x.id)

Perhaps through the class org.eclipse.ocl.uml.OCL. Is there a way to do this?
The method getOwnedComments() of org.eclipse.uml2.uml.Constraint always return null.

List <Constraint> constraints = myOCL.parse(document);
for (ct Constraint: constraints) {
         System.out.println (ct.getOwnedComments ());
}

The only way to do this is to do manually(through the manipulation of strings) ?

Regards,
John

Hi

The org.eclipse.ocl.ecore and org.eclipse.ocl.uml plugins use the old
LPG parser for which you can find start and end text offsets in the
CSTNodes. So you can certainly use these to scan for additional text. It
is a long time since I looked at this code. My recollection is that the
CSTNodes also have the LPG start and end tokens from which you can find
the comments as 'adjuncts'. The normal lex+parse+analyze takes you
straight from text via CST to AST. To get at the intermediate CST, you
will need to invoke only the lex+parse phases.

The new org.eclipse.ocl.examples.xtext plugins use Xtext and so support
editors. Comment support has been added so that /** .. */ comments are
automatically interpreted as UML Comments or Ecore documentation
EAnnotations and contribute to hover text. -- ... comments remain text only.
