want to extract entities connected to function in model using Script

I have one model which is having one function entities in it.

I want to extract all objects that are connected to function(sub process activity) entitiy

like:- bussiness rules, Application system type etc.

I used below mentioned  constants.EDGE_OUT  for  extracting all activity which are connected to function with outer edge. I tried this in a different model it is working fine. 

Now which constant name I have to use to extract "Application System Type" and "Business Rule" which is connected to function using a plain line(like- supports and describess).

please help me guys....

it's very urgent....

var connList = occlist[obj_count].Cxns(Constants.EDGES_OUT);
