The HL7 component ships with a HL7 data format that can be used to marshal or unmarshal HL7 model objects.
To use the data format, simply instantiate an instance and invoke the marshal or unmarshal operation in the route builder:
In the sample above, the HL7 is marshalled from a HAPI Message object to a byte stream and put on a JMS queue.
Here we unmarshal the byte stream into a HAPI Message object that is passed to our patient lookup service.
There is a shorthand syntax in Camel for well-known data formats that are commonly used.
