AggregateProcessor	An implementation of the Aggregator pattern where a batch of messages are processed (up to a maximum amount or until some timeout is reached) and messages for the same correlation key are combined together using some kind of AggregationStrategy (by default the latest message is used) to compress many message exchanges into a smaller number of exchanges.
AggregationStrategyBeanAdapter	An AggregationStrategy that adapts to a POJO.
AggregationStrategyBeanInfo	Class information about the POJO method to call when using the AggregationStrategyBeanAdapter.
AggregationStrategyBiFunctionAdapter	An AggregationStrategy that adapts to a BiFunction.
AggregationStrategyMethodInfo	Method information about the POJO method to call when using the AggregationStrategyBeanAdapter.
AggregationStrategyParameterInfo	Parameter information to be used for method invocation.
DefaultAggregateController	A default AggregateController that offers Java and JMX API.
GroupedBodyAggregationStrategy	Aggregate body of input Message into a single combined Exchange holding all the aggregated bodies in a List of type Object as the message body.
GroupedExchangeAggregationStrategy	Aggregate all exchanges into a single combined Exchange holding all the aggregated exchanges in a List of Exchange as the message body.
GroupedMessageAggregationStrategy	Aggregate all Message into a single combined Exchange holding all the aggregated messages in a List of Message as the message body.
MemoryAggregationRepository	A memory based AggregationRepository which stores Exchanges in memory only.
OptimisticLockRetryPolicy	Class to control how failed optimistic locks are tried.
