Package org.aksw.jena_sparql_api.algebra.transform

Class TransformAddFilterFromExtend

java.lang.Object
org.apache.jena.sparql.algebra.TransformCopy
org.aksw.jena_sparql_api.algebra.transform.TransformAddFilterFromExtend
All Implemented Interfaces:
org.apache.jena.sparql.algebra.Transform
public class TransformAddFilterFromExtend extends org.apache.jena.sparql.algebra.TransformCopy
Given extend(subOp, ?var: 'value') it adds an extra filter filter(extend(subOp, { ?var: 'value'}), { ?var: 'value'}) This is used to streamline satisfiability checking. The inverse transformation is TransformRedundantFilterRemoval
