    • prefetch

      protected Iterator<org.apache.jena.graph.Triple> prefetch() throws Exception
      Returns an iterator over the triples generated by instancing the template with each of the result set rows. Duplicates are not removed; this can be achieved by wrapping this iterator with a UniqueIterator. TODO We could do some optimization by factoring out constant triples from the template.
