The Stubcode Generation Wizard creates a subfolder whose name matches the prefix you specified in the Prefix field; in this case, the subfolder is named HL7. This subfolder is located in the same folder as your VMD file. In this subfolder, the following classes are created by this tutorial example:

• An Engine class, stored in HL7Engine.cs;
• A Message class, stored in LabResultMessage.cs;
• Table classes, stored in MessageInfoTable.cs, ObservationRequestTable.cs, ObservationResultTable.cs and PatientTable.cs;
• TableRow classes, stored in MessageInfoTableRow.cs, ObservationRequestTableRow.cs, ObservationResultTableRow.cs and PatientTableRow.cs.

The Engine class represents the Chameleon engine that actually parses and classifies the HL7 messages. From this class, you can access the Message classes that have been created.

	The name of the Engine class corresponds to the prefix you specified; in this tutorial, because the prefix is HL7, the Engine class is named HL7Engine.

The Message class represents the message definition you specified in your VMD file. The interface to this class enables you to access the Table and TableRow classes. You can access any row of any defined table or, if you prefer, each table in its entirety. One message class is defined for every message you create.

	The Message class inherits from the Message class that is predefined in Chameleon. The parent Message class contains a method, GenerateMessage, that can generate an HL7 message based on the information it has obtained from your VMD file. This message is returned as a text string.

Each Table class represents a table you created when building your VMD file. This class enables you to access any row of the table. One Table class is created for every table you define.

Each TableRow class represents a row of its table. The TableRow objects are accessed from the Table class. One TableRow class is created for every table you define.
