[great-users] negative application condition

[Arda Göknil]

I could not write a good example. I mean, the meta association. I imagine  the A, B and C classes are the meta classes and the association between them are the meta association, there is not a meta class named Association. The setting the pattern cardinality to "-1" is true if there is a Association entity in the meta class.

  As far as I remember you can set the pattern cardinality on the association between B and C to be “-1” instead of setting it on B. 
   
  I don’t know if things have changed in the recent past but earlier the value for negative condition used to be “0” not “-1”.
   
  Could Attila or Feng please comment to this?
   
  Thanks,

      Hi,

    I have a question about the negative application condition in GREAT. In the user manual, it is said that if you set the pattern cardinality to "-1", you negate that element. but I want to negate the element for only one association.

    For example, in my pattern I have three classes: classA, classB and classC. ClassA has a relation with ClassB and ClassC but I do not want ClassB to have a relation with ClassC. I want to negate ClassC for the association between ClassB and ClassC. But in my pattern if I set the pattern cardinality to -1, I can not show the whole pattern in one rule. How is it possible?

    Regards,
