org.ow2.petals.se.eip.patterns
Class Aggregator

java.lang.Object
  org.ow2.petals.se.eip.patterns.AbstractPattern
      org.ow2.petals.se.eip.patterns.Aggregator

All Implemented Interfaces:

Pattern

public class Aggregator
extends AbstractPattern

Receives a bunch of messages and identifies messages that are correlated (XPATH expression). Once a complete set of messages has been received (XPATH expression on special message to decide that the set is complete), the aggregator collects information from each correlated message and publishes a single, aggregated message to the output channel for further processing. It returns the result to this special message if it exists.
