Marshalling and Message Consumers
On reception of a Broker event, the message consumer performs the reverse operation from that of the message producer. Normally, the message consumer converts the Broker event into a JMS message of the appropriate type, then passes the message to the JMS client. If a MarshalIn object is defined, the message consumer hands the Broker event to the MarshalIn object and passes the returned JMS message to the JMS client.
