[HAPI-devel] Detemining the Message type in Application.processMessage(...)

[Steve P. <st...@pr...>]

Could someone please tell me how one goes about determining what type of
message has been received in the Application.processMessage(Message in)
method?

Here's a code snippet, which is being sent an ADT_A01 msg, but I have no
idea how to determine that it is an ADT_A01.  All I want to do is determine
which message type was sent, get the data I need, then send an ACK.  

public class ABApplication implements Application
{
...
    public Message processMessage(Message in) throws ApplicationException
	{
        Message out = null;
		PipeParser parser =  new PipeParser();

        try
		{
			System.out.println("\nmsg Name: " + in.getName());
			System.out.println("\nmsg Name: " +
in.getClass().getName());
			System.out.println("\nmsg Version: " +
in.getVersion());
			System.out.println("\nmsg ?: " +
in.get("MSH").getName());

			String[] names = in.getNames();

			for (int i = 0; i < names.length; i++)
				System.out.println("** " + names[i]);
...

Here's the output:

msg Name: GenericMessage$V22

msg Name: ca.uhn.hl7v2.model.GenericMessage$V22

msg Version: 2.2

msg ?: MSH
** MSH
** EVN
** PID
** NK1
** PV1

Thanks,
