Detailed Description

An instance of MDFDocument represents one machine object model for the editor.

Part of the wxWindows document/view framework. Opening and saving of documents is passed through this class to the xml reader/writer components. When a new document is created or opened, this class initializes a new model. Document's model can be accessed with the getModel() method.
