Enabling Streaming Expand in a Custom Application

You can enable a streaming expand in a custom application.

  1. Open BusinessObject.java.

  2. Replace the following section: 

    Expansion expansion = bo.expandSelect(cntx, relPattern, 
typePattern,busSelects, relSelects, getTo, getFrom, levels, 
limit, checkHidden);

    BusinessObjectWithSelect root = expand.getRootWithSelect();

    RelationshipWithSelectList rels = expand.getRelationship();

    for (int i=0; i<rels.size(); i++) {

    RelationshipWithSelect rel = rels.elementAt(i);

    ?

    }

    With this: 

    ExpansionIterator itr = bo.getExpansionIterator(cntx, 
relPattern, typePattern,busSelects, relSelects, getTo, getFrom, 
levels, limit, checkHidden, preventDups, pageSize);

    BusinessObjectWithSelect root = itr.getRoot();

    while (itr.hasNext()) {

    RelationshipWithSelect rel = itr.next();

    ?

    }
