public class QueryIterAddTripleTerm
extends QueryIterProcessBinding

Add (var, matchTriple) to a QueryIterator.

The supplied triple is a triple pattern which is grounded by replacing variables with terms from the current binding. It is an error not to have substitutions for all variables and results in the original binding unchanged.
