What you'll learn:
- Understand what structural design patterns are
- How structural patterns help create bigger structures through inheritance & composition
- Use adapter to convert an incompatible interface into a compatible one
- Simply the complex interfaces of a system through facade
- Use proxy to control access to an object
- Understand how decorator can be used to add more behaviors to an object at runtime
- Form larger structures through recursive composition through composite
- Enable sharing of large number of objects through flyweight
- Separate abstraction & its implementation to provide variations without implementing too many classes
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 Structural 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. 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 structural 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.
