Class HL7DataFormat

java.lang.Object
  org.apache.camel.component.hl7.HL7DataFormat

All Implemented Interfaces:

org.apache.camel.spi.DataFormat

public class HL7DataFormat
extends Object
implements org.apache.camel.spi.DataFormat

HL7 DataFormat (supports v2.x of the HL7 protocol).

This data format supports two operations:

• marshal = from Message to String (can be used when returning as response using the HL7 MLLP codec)
• unmarshal = from String to Message (can be used when receiving streamed data from the HL7 MLLP codec). This operation will also enrich the message by adding the MSH fields (MSH-3 to MSH-12) as headers on the message.

Uses the HAPI (HL7 API) for HL7 parsing.

Uses the default GenericParser from the HAPI API. This DataFormat only supports both the EDI based HL7 messages and the XML based messages.

The unmarshal operation adds these MSH fields as headers on the Camel message (key, MSH-field):

• CamelHL7SendingApplication = MSH-3
• CamelHL7SendingFacility = MSH-4
• CamelHL7ReceivingApplication = MSH-5
• CamelHL7ReceivingFacility = MSH-6
• CamelHL7Timestamp = MSH-7
• CamelHL7Security = MSH-8
• CamelHL7MessageType = MSH-9-1
• CamelHL7TriggerEvent = MSH-9-2
• CamelHL7MessageControl = MSH-10
• CamelHL7ProcessingId = MSH-11
• CamelHL7VersionId = MSH-12

All headers are String types.
