	It would be nice to have a VirtualCount stats property along with Count on SparqlResultSet objects when the source query specify a LIMIT clause, thus it would avoid running the query twice to get results and stats separately (not sure whether it is the best place, so I leave this to your consid&eacute;ration)</p>
<p>
	This property would get the number of results that would be returned without the LIMIT clause (or -1 if not supported by the underlying store/service, so I suppose it would be used mainly by InMemory store ?)</p>
<p>
	As it is, since I&#39;m not yet familiar with the library architecture, I coul not add at the sparqlResultSet level so I &quot;hacked&quot; it into the SparqlQuery object instead.</p>
<p>
	Here are the modifications I made (sorry to get those as is, I&#39;m trying !! but I&#39;m also not very familiar with the tools you use, though I hope to be able to collaborate more in the future)</p>
