 /**
 34  
  * <p>From an HL7 messaging perspective, a ReceivingApplication is a consumer of a messages. 
 35  
  * Once a parser parses an incoming message, the message would normally be forwarded 
 36  
  * to an application of some sort (e.g. a lab system) which would process the 
 37  
  * message in some way meaningful for it, and then return a response.</p>
 38  
  *   
 39  
  * <p>If you are wondering how to integrate HAPI into an existing server application, 
 40  
  * this is probably the place.  Create a class that implements ReceivingApplication, then look 
 41  
  * at HL7Server and ApplicationRouter to see how to get HAPI to listen for messages on 
 42  
  * a socket and pass them to your ReceivingApplication.</p>
 43  
  * 
 44  
  * Note that this interface replaces ca.uhn.hl7v2.app.Application in HAPI 0.5.
