Class SortedServiceReferenceList

java.lang.Object
ddf.catalog.util.impl.SortedServiceReferenceList
All Implemented Interfaces:
Iterable<org.osgi.framework.ServiceReference>, Collection<org.osgi.framework.ServiceReference>, List<org.osgi.framework.ServiceReference>, SequencedCollection<org.osgi.framework.ServiceReference>
public class SortedServiceReferenceList extends Object implements List<org.osgi.framework.ServiceReference>
This utility object sorts ServiceReferences by their service rankings first and then breaks ties with service ids.

It is an implementation of List but is backed by a sorted TreeSet of where the ServiceReference objects are what is used to maintain the list order.
