Class EquivalencesDAGImpl<T>

java.lang.Object

it.unibz.inf.ontop.spec.ontology.impl.EquivalencesDAGImpl<T>

All Implemented Interfaces:

EquivalencesDAG<T>, Iterable<Equivalences<T>>

public class EquivalencesDAGImpl<T>
extends Object
implements EquivalencesDAG<T>

DAG from an OntologyGraph The vertices of the DAG are equivalence sets (Equivalences) The edges form the minimal set whose transitive and reflexive closure coincides with the transitive and reflexive closure of the ontology graph
