Example: the memento pattern: Programming Foundations: Object-Oriented Design (2012)

The Memento design pattern is a simple but creative programming approach to undoing a change to an object. It involves creating an object with the Memento class that simply details how to go back to the state before the change was made. The solution works because it's set up in a way that means the object still manages itself. See the solution explained in more detail in this online video "Example: the memento pattern."
