A friend of mine asked me to suggest YouTube channels, vlogs, or blogs that I follow to develop my technical skills as a Software Developer. I’ve never thought about it concisely but I found out that there are few resources […]
The Decorator pattern (also known as Wrapper) is another pattern that categorized as a structural pattern and its intent: Attach additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality. Let’s assume than we […]
Facade pattern comes under structural patterns group, it aims to simplify connection between clients and complex subsystems by providing a simple interface that contains the needed functionalities by clients and redirect requests to the handlers in the subsystem. Lets see […]
In software and the real world, there are objects with different structures some of them are primitive or simple and some consist of other objects (Children) and many of these children consist of other objects and that is ok, but the problem […]
It’s time for the Bridge pattern. The Bridge pattern (also known as Handel/Body) is one of the structural patterns which its intent is: Decouple an abstraction from its implementation so that the two can vary independently. That’s the textbook definition, but let’s […]
Till now all the patterns that we talked about are creational design patterns, and as we said before creational design patterns abstract the instantiation process and help to make the system independent of how its objects are created, composed, and […]
Design patterns split into three main categories Creational, Structural and Behavioral, we explored the creational patterns and now we will move on to the second category the Structural patterns. These patterns focus on how to assemble objects and classes to […]
The design patterns differ in their usage and implementation, and each one of them provide a solution for many common problems with more efficient and flexible methods, one of the famous patterns is Prototype and it belongs to the creational […]
This week I will talk about another creational design pattern which is Factory Method (aka Virtual Constructor). Last week I talked about the Abstract Factory pattern, the Abstract Factory with the Factory Method both are considered factories that encapsulate the object […]
As a part of our new design patterns series, I will talk about Builder pattern which is the second pattern in our reference book “Design Patterns: Elements of Reusable Object-Oriented Software” by the Gang of Four. Builder pattern belongs to […]
