Retrieving the value of an attribute in a Java search graph using attribute name?

Given a SGraph for a result returned by the Search Service (using Java) what is the cleanest method of retrieving the value for one specific attribute, when there are many attributes with the same data type?

Eg. if a search is configured to return the following string attributes

  ...  singleSearchRequest.getResultTransformationSpec().add("OTName");  singleSearchRequest.getResultTransformationSpec().add("OTDataID");  singleSearchRequest.getResultTransformationSpec().add("OTParentID");  ...

Then when the first result returned iterated in this manner

  SGraph sGraph = sResultPage.getItem.get(0);  for (SNode sNode : sGraph.getN()) {     for (Object sAttVal : sNode.getS()) {      System.out.print(sAttVal + " (S)| ");    }  }

the three values returned are not in the order they were added to the transformation spec. This makes sense as a List doesn't have any ordering, so I expected to find a method along the lines of

sNode.getS(String attributeName)

to allow me to do something like

  SGraph sGraph = sResultPage.getItem.get(0);  for (SNode sNode : sGraph.getN()) {       System.out.print(sNode.getS("OTParentID") + " (S)| ");  }

but I can't find such a method, which tells me I'm thinking about this in the wrong way.

Any suggestions?

Have you seen a awesome sample in this forum pinned on the top by Kyle?

I used that in some code if I am using CWS although OT says to

Use the search API for better output control

Ciao, Appu

Thanks for the reminder, Appu. After re-reading it a few times the sample finally got me started down the right path.

This seems to achieve the desired result:

 SGraph sGraph = sResultPage.getItem.get(0);  for (SNode sNode : sGraph.getN()) {     System.out.print(sNode.getS().get(          // obtain the index of the specified column using the attribute name          sResultPage.getType().get(0).getStrings().indexOf("OTParentID")       ) + " (S)| ");  }
