Hello Greg, I can understand that this is a bit misleading, but the methods you used just work for VALUES clause "outside" of the query pattern:
|String ||queryString ||= ||"PREFIX dc: <http://purl.org/dc/elements/1.1/> ||\n||"||||||+ ||"PREFIX : <http://example.org/book/> ||\n||"||||||+ ||"PREFIX ns: <http://example.org/ns#> ||\n||"||||||+ ||"||\n||"||||||+ ||"SELECT ?book ?title ?price||\n||"||||||+ ||"{||\n||"||||||+ ||" ||\n||"||||||+ ||" ?book dc:title ?title ;||\n||"||||||+ ||" ns:price ?price .||\n||"||||||+ ||"}||||+ VALUES ?book { :book1 :book3 }"||; | I don't know if there is any convenient method, but the VALUES clause in query is inside an ElementGroup which contains a list of Element objects, with the VALUES clause being of type ElementData: check this code |ElementWalker.walk(query.getQueryPattern(), new ElementVisitorBase() {||||||||||@Override||||public void visit(ElementData el) {||||System.out.println(el||);||||}||||||||||});| If the VALUES clause is always in first position, it might work with |List<Var> valueVars = ((ElementData)((ElementGroup)query.getQueryPattern()).get(||0||)).getVars();| if not, you have to iterate over all elements and check which one is the VALUES element. Maybe one of the devs knows a better solution indeed ...
