Examples of UseLatestAggregationStrategy

org.apache.camel.processor.aggregate.UseLatestAggregationStrategy
An {@link AggregationStrategy} which just uses the latest exchange which is usefulfor status messages where old status messages have no real value; another example is things like market data prices, where old stock prices are not that relevant, only the current price is. @version $Revision: 1.1 $
