org.openrdf.query.algebra.evaluation.EvaluationStrategy.evaluate()
Evaluates the tuple expression against the supplied triple source with the specified set of variable bindings as input. @param expr The Tuple Expression to evaluate @param bindings The variables bindings to use for evaluating the expression, if applicable. @return A cursor over the variable binding sets that match the tupleexpression.
