Class ExprEvaluatorPartialOld

java.lang.Object

org.aksw.sparqlify.core.algorithms.ExprEvaluatorPartialOld

All Implemented Interfaces:

ExprEvaluator

public class ExprEvaluatorPartialOld
extends Object
implements ExprEvaluator

Evaluator for expressions. Transforms SPARQL expressions so that they can be translated to SQL. Concretely, this class attempts to remove all type constructors from the expressions. If not all of an expressions' variables are bound, it tries to evaluate as much as possible; hence the name "partial" evaluator.
