Class IVComparator

java.lang.Object

com.bigdata.bop.solutions.IVComparator

All Implemented Interfaces:

Serializable, Comparator<IV>

public class IVComparator
extends Object
implements Comparator<IV>, Serializable

A comparator that compares IVs according the SPARQL value ordering as specified in SPARQL Query Language for RDF. This implementation is based on the openrdf ValueComparator but has been modified to work with IVs.

Note: SidIV are blank nodes. However, we order SIDs after normal blank nodes since they are modeling somewhat different information.
