Sequence Diagram return a new constructed Object

I am drawing a Sequence Diagram where the scenario is. 1. an Actor calls :Table::query(query:String)

2. :Table::query Calls :Connection::execute(query)
3. :Connection::execute <> a new :Row Object
4. :Connection开发者_JAVA百科::execute calls :Row::fillData(result)
5. :Connection::execute returns :Row
6. ...... There are More

But I am Stuck in Step 5

I cant Understand how to draw that, :Connection::execute returning the newly Constructed Row itself, in a Standard way.

Hmm, maybe simple return message from :Connection to :Table with that result will suffice: sequence diagram with workflow described in the question, result is carried by the return/reply message http://www.freeimagehosting.net/uploads/e33283f7af.png
