What you'll learn:
- Understand what creational design patterns are
- How creational design patterns solve object construction problems
- Implement singleton correctly in C++ with thread-safety
- Use factory method to encapsulate the construction process
- Use object pool pattern to avoid repetitive construction & destruction of objects
- Control construction process of an object through builder
- Clone expensive objects through prototype
- Use abstract factory to construct objects based on a context
Design Patterns are a way to solve common object oriented design problems. But understanding and learning design patterns is hard and takes time. Looking at a pattern is like looking at a solution without a problem, unless you've encountered the problem in the past.
This course aims to help you understand &implement Creational Design Patterns. Each pattern is explained with multiple examples and through modern C++. This helps you understand how the pattern can be implemented efficiently using language features. The examples do not involve cars, pizzas, ducks, coffee, etc. These topics are rarely used while building real-world software. Instead Iprovide real-world examples written in Modern C++. These examples will compile &execute on any platform that supports a C++compiler.
This is how the course teaches creational patterns.
The intent, structure of the pattern is explained through UML class diagram.
Basic implementation details of the pattern are explained.
The pattern is implemented in a simple example.
You get familiar with the overall implementation of the pattern.
Another example is introduced that has design issues the pattern aims to resolve.
We examine the issues and refactor the code by applying the design pattern step by step.
Alternative scenarios &examples are explained along with differences between them. You also learn how to decide between different alternatives.
I discuss the pattern in context of C++ and how to tweak it for performance, reusability &maximum flexibility.
Finally, you'll learn when to use the pattern and its pros &cons.
This is an intensive discussion that spans multiple lectures. At the end of each section, you'll understand the pattern in depth and can apply it in your code or easily clear any design interview.
