Example: Memento Pattern

The Memento pattern is a classic behavioral design pattern that allows you to capture the internal state of an object as a memento object without violating encapsulation. You can then restore this memento state later.

In UI application development, the Memento pattern is commonly used to implement an undo/redo feature.

Implementing the Memento pattern typically requires a lot of boilerplate code.

In this series

In this series, we will see how to automatically implement this pattern using Metalama.

We start with the most trivial implementation and progressively add new features:
