Class HL7MessageConverter

java.lang.Object

org.openehealth.ipf.platform.camel.hl7.converter.HL7MessageConverter

All Implemented Interfaces:

MessageConverter

public class HL7MessageConverter
extends Object
implements MessageConverter

HL7MessageConverter helps serializing a HL7 message to and from a string for the purpose of routing it through a JMS queue. The same converter should be used on consumer and producer side.

HAPI HL7 message objects have a reference to a transient parser, which in return has the reference to the valid HapiContext. After deserialization, the context and parser references have to be re-established.

Currently, this class accepts String and HAPI message objects only. Deserialization will always produce a HAPI Message object.
