Description copied from interface: EvaluationStrategy

Evaluates a @{link TupleExpr} under an iteration of @{link BindingSet}s.

Parameters:

tupleExpr - the expression to evaluate

bIter - a closable iteration of @{link BindingSet}s to be used as different BindingSets on the variables of the tupleExpr

Returns:

a closable iteration that contains @{link BindingSet}s on the variables of the tupleExpr

Throws:

org.openrdf.query.QueryEvaluationException - when the evaluation fails
