public class Resequencer
extends AbstractAggregator

Resequencer is used to resequence events according to their dispatch sequence in the correlation group. When the message splitter router splits an event it assigns a correlation sequence to the individual message parts so that another router such as the Resequencer can receive the parts and reorder or merge them.
