// This will walk through all parts of the query
ElementWalker.walk(q.getQueryPattern(),
// For each element...

// ...when it's a block of triples...
public void visit(ElementPathBlock el) {
// ...go through all the triples...

while (triples.hasNext()) {
// ...and grab the subject
// if (triples.next().getObject().isLiteral()) {
// literalsList.add(triples.next().getObject()
