Package org.aksw.jena_sparql_api.algebra.transform

Class TransformRedundantFilterRemoval

java.lang.Object
org.apache.jena.sparql.algebra.TransformCopy
org.aksw.jena_sparql_api.algebra.transform.TransformRedundantFilterRemoval
All Implemented Interfaces:
org.apache.jena.sparql.algebra.Transform
public class TransformRedundantFilterRemoval extends org.apache.jena.sparql.algebra.TransformCopy
Remove filters in patterns such as OpFilter(OpExtend(constant AS ?x, (subOp)), ?x = constant) Currently this works only if the OpExtend is an immediate child of OpFilter Mainly needed as a workaround for Virtuoso...
