Class TransformPathFlatternStd

java.lang.Object

com.hp.hpl.jena.sparql.algebra.TransformCopy

com.hp.hpl.jena.sparql.algebra.optimize.TransformPathFlatternStd

All Implemented Interfaces:

Transform

public class TransformPathFlatternStd
extends TransformCopy

The path transformation step exactly as per the SPARQL 1.1 spec. It does not produce very nice execution structures so ARQ uses a functional equivalent, but different, transformation.
