Class Iso

java.lang.Object

org.apache.jena.sparql.util.Iso

public class Iso
extends Object

Isomorphism utilities, based on in-order lists. See IsoMatcher for isomorphism for un-ordered collections. In this class, "isomorphism" is based on the policy in NodeIsomorphismMap, which is blank node isomorphism unless NodeIsomorphismMap.makeIsomorphic(org.apache.jena.graph.Node, org.apache.jena.graph.Node) is overridden.
