title: Get all objects from a GWT CellTable
body: <p>Simple question: I have a CellTable filled with Keyword objects. Now, I would like to retrieve all the Keywords in that CellTable. Is this possible? If not, why? Surely there must be a way...</p>
  
  <p>I can not understand how this is so hard (well maybe it isn't but I just can't seem find the answer for the life of me).</p>
  
  <p>Some code to clarify:</p>
  
  <pre><code>//my celltable
  private CellTable&lt;Keyword&gt; ctKeywordsLinked = new CellTable&lt;Keyword&gt;();
  
  //listdataprovider to fill my celltable with
  private ListDataProvider&lt;Keyword&gt; dataProviderLinkedKeywords = new ListDataProvider&lt;Keyword&gt;();
  
  //add 4 keyword objects to the listdataprovider to fill the celltable
  dataProviderLinkedKeywords.getList().add(new Keyword);
  dataProviderLinkedKeywords.getList().add(new Keyword);
  dataProviderLinkedKeywords.getList().add(new Keyword);
  dataProviderLinkedKeywords.getList().add(new Keyword);
  </code></pre>
  
  <p>So now that I have my celltable filled, I would like to retrieve those 4 keywords without touching the listdataprovider. I hope everything is a bit more cleared up :-)</p>
