Obtain relationships to objects outside of current model.

I am hoping someone in the community has an easy answer to this question.

I am trying to obtain all external relationships between models. These are the ones that do NOT have a checkmark next to them in the relationship column of Properties^Relationships. E.g. I only want the bottom three relationships.

I am currently using this code:

aCnxOcc = aObjOcc[j].Cxns(Constants.EDGES_IN); // CxnOcc[] in model; don't care about both directions.

             

             // determine each relationship from an object.

             for(var k=0; k < aCnxOcc.length; k++) {

                 // determine if target object is within the same model use ObjDef from TargetObjDef()

                 var myObjOccSource = aCnxOcc[k].getSource().getObjDefName(g_nloc);  //ObjOcc

                 var myObjOccTarget = aCnxOcc[k].getTarget().getObjDefName(g_nloc);  //ObjOcc

                 var myCxnDef = aCnxOcc[k].getDefinition();

Thanks,

MR
