All Implemented Interfaces:

Smusher

public class TransitivitySmusher
extends FixedQuerySmusher

This smusher computes the transitive closure of a given predicate (by default owl:sameAs). e.g if it finds that A owl:sameAs B and B owl:sameAs C then it returns A and C as a match. This smusher itself does not iterate and thus it will not return the complete closure. It needs to be used inside an IterativeSmusher to compute the complete closure. As it uses a single query it works only on a single repository, not in cases when we need to smush things in different repositories.
