There are 4 types of collections in OTrunk:

OTResourceList, OTResourceMap, OTObjectList, OTObjectMap

In all cases you should not use a set method in your OTClass. You only add a get method. The list object will be created automatically when it is requested.

An example on how to create an OTResourceList:

1. Add a sample list to your OTML file:

   <scoreList>
   <string>5</string>
   <string>4</string>
   <string>2</string>
   <string>1</string>
   </scoreList>
   

1. Add your desired list to your OT interface

	
public OTResourceList getScoreList();

1. Next update its corresponding controller and process the values as you see fit

   OTResourceList scores = otObject.getScoreList();
   		
   List<Integer> scoresList = new ArrayList<Integer>();
   		
   for (int i = 0; i < scores.size(); i++){
      String s = (String)scores.get(i);
      scoresList.add(new Integer(s));
   }
   	
   realObject.setScores(scoresList);
