Package org.aksw.jena_sparql_api.algebra.transform

Class TransformPullFilters

java.lang.Object
org.apache.jena.sparql.algebra.TransformCopy
org.aksw.jena_sparql_api.algebra.transform.TransformPullFilters
All Implemented Interfaces:
org.apache.jena.sparql.algebra.Transform
public class TransformPullFilters extends org.apache.jena.sparql.algebra.TransformCopy
Pull filters up so that they may be distributed over a join Example: Join( Filter({_?v1_}), ?v1=_), { _?v1_ }) Becomes: Filter(Join({_?v1_}, {_?v1_},?v1=_)) Allows: Subsequent filter placement: Join( Filter({ _?v1_}), ?v1=_), Filter({ _?v1_ }, ?v1=_)
