Difference-Between-Command-Memento-Design-Pattern

In software engineering, Behavioural Design Patterns deal with the assignment of responsibilities between objects which in turn make the interaction between the objects easy & loosely coupled. In this article of the Behavioural Design Patterns, we’re going to take a look at Command Design Pattern in Modern C++ which encapsulate all the details related to operation into a separate object. Command Design Pattern is widely used in sophisticated software. In fact, you might be using it every day without even knowing that....

Memento Design Pattern in Modern C++ is a very straight forward Behavioural Design Pattern. The motivation behind using the Memento Design Pattern is to keep some sort of token which then allows you to restore an object to a particular state. This is particularly useful if you have a system with medieval components i.e. an object or indeed a set of objects goes through a set of changes. By the way, If you haven’t check out my other articles on Behavioural Design Patterns, then here is the list:...
