Purpose of X Classes is to provide getter and setter method to Model classes. X Classes are the properties classes, which are based on a database tables. Whenever you change the fields of a table you need to update its X class.
M Classes are used to write business logic and it extends X Classes for getter and setter method. If a tab of window using a workflow processes with node have Document Action functionality, then M Class should implements DocAction class.
With the help of X-Classes and M Classes, business logic for the window will be created.
Following is an example of an X-Class :
