Class DefaultComparator

java.lang.Object
  org.apache.servicemix.eip.support.resequence.DefaultComparator

All Implemented Interfaces:

Comparator<javax.jbi.messaging.MessageExchange>, SequenceElementComparator<javax.jbi.messaging.MessageExchange>

public class DefaultComparator
extends Object
implements SequenceElementComparator<javax.jbi.messaging.MessageExchange>

Compares MessageExchange sequence elements based on sequence numbers defined by their in-NormalizedMessages. This comparator works on sequence numbers of type Long. Sequence numbers must be stored as NormalizedMessage properties. The property name under which the sequence number is stored is configured via this comparator's sequenceNumberKey property.
