| RDFClauseIterator | | class RDFClauseIterator extends AbstractClauseIterator implements RDFLogger,RDFConstants(Code) | | Clause set iterator implementation.
Each iterator instance has its own jena model which is NOT re-used.
This simply means that the RDF documents is read / parsed whenever the application
requests an iterator - caching could be implemented here, but this is curremntly not implemented.
