Class TransformExprToBasicPattern

java.lang.Object
org.apache.jena.sparql.algebra.TransformCopy
org.aksw.jena_sparql_api.algebra.transform.TransformExprToBasicPattern
All Implemented Interfaces:
org.apache.jena.sparql.algebra.Transform
public class TransformExprToBasicPattern extends org.apache.jena.sparql.algebra.TransformCopy
Transform expressions to property functions. Transform function calls in expressions, such as internalIdOf(?x) to a triple pattern ?x internalIdOf ?y - with ?y being a fresh variable for the expressions result.
