Introduction The Decorator pattern can be used to dynamically alter or add functionality to existing classes. This pattern is oftern more efficient than subclassing because it relieves us of the need of defining a new object. So, what does it…
Introduction The flyweight pattern is a pattern that helps minimize memory usage by sharing and reusing data. A common example is wordprocessor where each character not only holds the character like ‘A’ but also things like markup and formatting data.…
Introduction Just for fun and to try out Rust operator overloading capabilities, I decided to write a quaternion library. If you don’t know what quaternions are, they are basically complex numbers on steroids. If you want to know more, there…
Introduction The Chain of Responsibility (CoC) pattern describes a chain of command/request receivers. The client has no idea which one of the receivers will handle the request. The beauty of the pattern is again uncoupling: the sender and the receiver…

Introduction The singleton pattern restricts the instantiation of a class to a single instance. The singleton pattern makes it possible to ensure that: One of the main uses of the singleton pattern is logging, as all clients who wish to…

Introduction The command pattern is a behavioral design pattern. It is used by an Invoker to perform one action or a series of actions on objects, called Receivers. The Invoker is unaware of the nature of the receiving objects, it just knows about…

Introduction The facade pattern is used as a way to hide more complex logic. A facade can do the following: A facade pattern is typically used in the following cases: What does it look like? Well, it is quite simple:…

Introduction The Interpreter pattern can be used to interpret and evaluate sentences in a language. The idea is to make a class for each symbol, both terminal and non-terminal and construct a syntax tree which can be evaluated and interpreted.…

Introduction The mediator pattern is a pettern used when you want to simplify communication i.e. message dispatching in complex application. It involves building a mediator where each object can delegate its communication, it also routes the messages to the right…
