title: Mongodb Java MapReduce getOutputCollection
body: <p>I don't know anything about the OutputTypes. I'm trying something like this:</p>
  
  <pre><code>output=collection.mapReduce(map,reduce,null,
    MapReduceCommand.OutputType.INLINE,null);
  collection=output.getOutputCollection();
  </code></pre>
  
  <p>But the collection is null, because of the INLINE output type. I need the reduced collection because I need to reduce it further. How could I do this?</p>
