Interface Application

All Known Implementing Classes:

AcceptApplication, DefaultApplication, MessageTypeRouter, MultiTestApplication, ProfileTestApplication, TestApplication

public interface Application

From an HL7 messaging perspective, an Application is a consumer of a messages. Once a parser parses an incoming message, the message would normally be forwarded to an Application of some sort (e.g. a lab system) which would process the message in some way meaningful for it, and then return a response.

If you are wondering how to integrate HAPI into an existing server application, this is probably the place. Create a class that implements Application, then look at Responder and SimpleServer to see how to get HAPI to listen for messages on a socket and pass them to your Application.
