Examples of AggregationStrategy

org.apache.camel.processor.aggregate.AggregationStrategy
A strategy for aggregating two exchanges together into a single exchange. Possible implementations include performing some kind of combining or delta processing, such as adding line items together into an invoice or just using the newest exchange and removing old exchanges such as for state tracking or market data prices; where old values are of little use. @version $Revision: 1.1 $
