Interface ExchangeFactory

All Superinterfaces:
AutoCloseable, CamelContextAware, HasCamelContext, NonManagedService, PooledObjectFactory<Exchange>, RouteIdAware, Service
public interface ExchangeFactory extends PooledObjectFactory<Exchange>, NonManagedService, RouteIdAware
Factory used by Consumer to create Camel Exchange holding the incoming message received by the consumer.

This factory is only for Consumer's to give control on how Exchange are created and comes into Camel. Each Camel component that provides a Consumer should use this ExchangeFactory. There may be other parts in Camel that creates Exchange such as sub exchanges from Splitter EIP, but they are not part of this contract as we only want to control the created Exchange that comes into Camel via Consumer or PollingConsumer.

The factory is pluggable which allows using different strategies. The default factory will create a new Exchange instance, and the pooled factory will pool and reuse exchanges.
