Is there any documentation about the Undo and Redo?

[Li GuangQiang]

Hello, master of DDD

 

         I am very interested in the fact that DDD can perform Undo and Redo during debugging, and I am going to look in to how to achieve the function. I would like to know what information should be saved while you are performing Undo and Redo.

Is there any limitation of Undo or Redo? Have you made a specific stack for saving Undo and Redo information? Can you point out which part of the source code is responsible for this function?

I will greatly appreciate if you can give me some information about it.

 

Looking forward to your reply!

 

Best regards,

Aries
