Examples of ca.uhn.hl7v2.model.Message

ca.uhn.hl7v2.model.Message

Represents a complete HL7 message including all structures, segments, and fields.
Note this it is not recommended to implement this interface directly, as it is subject to change. Instead, extend abstract implementations for your model classes, such as {@link AbstractMessage} and {@link AbstractGroup}
