using "can be parent"

Created March 22, 2011 14:13

Hi,

i derived a PersistantProperty from baselang.Property. I could restrict the user to only use int and String for the type field by using childConcept...

e.g.

  can be parent
    (operationContext, scope, node, childConcept, link)->boolean {
      if (link == link/PersistentProperty : type/) {
        if (childConcept == concept/IntegerType/ || childConcept == concept/StringType/) {
          return true;
        } else if (childConcept == concept/ClassifierType/) {
          return true;
        }
        return false;
      }
      true;
    }

As one can see above, i also accept other Classes as types in my PersistantProperty. But if i use code completion, various classes are proposed as Type. But i just want my own classes proposed here - the are instances of BusinessObject. (BusinessObject extends ClassConcept).

How can i achieve this?

Any help appreciated,
Dan

Probably there is someone from Jetbrains who has an idea..I ll try to reformulate my issue:

My problem is that i want to restrain possible child nodes. Therefore i use a constraint "can be parent". I use the link field and the childConcept filed to restrain to specific Child-Concepts. But what if my childConcept is a ClassifierType. How can i get the Classifier the ClassifierType is pointing to?

Any ideas?

Hi!

You can try calling node.classifier:

node<ClassifierType> myNode;
node.classifier
