Link Constraint with oclIsKindOf [message #121619] Wed, 25 April 2007 07:55 Go to next message

Hello,

I have two Metamodels: Core and Entity (Entity knows Core). Core defines
something like ModelElement and Dependency. In the Editor I created a
LinkMapping to have Dependencies between entity::Entity and
entity::EntityConstants. Of cource, the the normal behavior is that one
can create Dependencies between all ModelElements and this is not what I
want. I want to restrict the Dependency creation to Entity ->
EntityConstants.
I tried to define link constraints like:
self.oclIsKindOf(EntityConstants)
self.oclIsKindOf(Entity)

This fails because Entity/EntityConstants seem to be unknown:
Invalid expression body 'self.oclIsKindOf(Entity)
'. Cause: Invalid expression body 'self.oclIsKindOf(Entity)
'. Cause: ERROR in (variableExpCS): (Unrecognized variable: (Entity))


Can anyone give me hint how to proceed.

Cheers,
Mathias

Hello Mathias,

Try using entity::EntityConstants as a parameter of oclIsKindOf.

Hello Alex,

I tried (in several variations: ::, : , fqn ...), but it does not work.

Hi Mathias,

Use both type names as qualified, the way Alex has suggested.
As you use two metamodels, it is unclear which package was taken
as the default one for resolving un-qualified names.

If you have tried so already, could you please post a simple test models
that we could reproduce this?

Regards,
/Radek

I am also facing the same prob

I hv two metamodels Tde & UseCase

All the elements in UseCase extends from DiagramElement which i hv defined
in Tde & also the diagram of usecase extends from class which i hv define
in Tde.


By the way UseCase is usecase editor & Tde is statemachine editor.
now when i define

self.ocliskindof(Actor) in usecase it gives error.

but when i define
self.ocliskindof(StartState) in Tde it works fine.

i tried to define

self.ocliskindof(Actor::DiagramElement) but still it gives error.

what i want is that i dnt want any incoming transition on actor

Thanks

Hi Varun,

Have a look at http://wiki.eclipse.org/index.php/GMF_Constraints#Java

Hi Varun,

It is not easy to see what erros you report here,
as you use 'ocliskindof' instead of 'oclIsKindOf'.
Also, 'Actor' used as type first and then as a package
in 'Actor::DiagramElement' indicates there might be other
causes of errors.

/Radek
