Class ServiceReferenceRankingComparator

java.lang.Object
  org.apache.stanbol.enhancer.servicesapi.helper.ServiceReferenceRankingComparator

All Implemented Interfaces:

java.util.Comparator<org.osgi.framework.ServiceReference>

public class ServiceReferenceRankingComparator
extends java.lang.Object
implements java.util.Comparator<org.osgi.framework.ServiceReference>

Compares ServiceReferences based on the Constants.SERVICE_RANKING property value. Highest Rank will be listed first.

TODO: This is a copy of the same Comparator within the "stanbol/commons/solr/core module" (org.apache.stanbol.commons.solr.utils.ServiceReferenceRankingComparator). However creating an own dependency because of that seemed also not the right thing to do.
