Bug in OCL or in my code? [message #658222] Mon, 07 March 2011 13:26 Go to next message

Hi,

I'm trying to generate some code for a c like language. It contains pieces like:

typedef struct
{
  BAR b;
} FOO;

typdef struct
{
  int i;
} BAR;


However, in this case the order of the typedefs matters. So the typedef of BAR should precede the one of FOO.

So I need to order a collection of types in my model. I decided to first generate a set of all types present in my model. Then, I'll put them in the right order based on a recursive function which looks like:

[query public sortTypes(done: Sequence(PG_Type), tobedone: Set(PG_Type)) : Sequence(PG_Type) =
if tobedone->isEmpty() then done
else
   let bottom  : Set(PG_Type) = tobedone->select(t| done->includesAll(subTypes(t))),
       newdone : Sequence(PG_Type) = done->union(bottom->asSequence()),
       newtobe : Set(PG_Type) = tobedone-bottom
   in
       sortTypes(newdone, newtobe)
endif
/]



When I run this code, I get an error in the log stating:
Evaluation failed with an exception: org.eclipse.ocl.util.BagImpl cannot be cast to java.util.Set

As far as I can see, the typecast is done in the calculation of newtobe. However, I'm not an expert in OCL and I'm curious about the return types of the various expressions.

Any clues?

Greetings,
Wilbert.

Hi Wilbert,

to reproduce your problem I've tried entering a similar expression into the OCL console after opening OCLEcore.ecore and selecting ocl/ecore/CallExp:

let done:Sequence(ecore::Constraint)=Sequence{}, tobedone:Set(Constraint)=Set{} in
if tobedone->isEmpty() then done
else
let bottom : Set(ecore::Constraint) = tobedone->select(t| true),
newdone : Sequence(ecore::Constraint) = done->union(bottom->asSequence()),
newtobe : Set(ecore::Constraint) = tobedone-bottom
in
Sequence{}
endif->isEmpty()
Results:
'Successfully parsed.'

Main difference to your expression is that I emulated the operation arguments by let-definitions and replaced the predicate in the select body by true to avoid having to define subTypes somewhere.

In particular, the tobedone-bottom expression which you suspect to be the offending one seems to parse fine in this scenario.

It would be cool if you could provide some more reproduction info for us. Also, a stack trace of the place where the mismatch is encountered may help.

Thanks and best,
-- Axel

Hi Axel,

I'm editing the code inside the Acceleo-3 editor. The editor itself does also not complain, so parsing the expression does not seem to be the problem.

In the meanwhile, I changed
	newtobe : Set(PG_Type) = tobedone - bottom

into
	newtobe : Set(PG_Type) = (tobedone->asSet()) - (bottom->asSet())


That solved(?) the issue. Sounds like I'm really forcing the evaluator to cast now (if something like that can happen).

In case it might be anyhelp, stack trace is attached below.

Greetings,
Wilbert.
