Summary
We began the chapter by understanding what Proxies are. We understood the basics of a Proxy and how it is used effectively in software architecture. You then learned about the Proxy design pattern and the context in which it's used. We looked at how the Proxy design patterns control access to the real object that provides the required functionality.
We also saw the pattern with a UML diagram and sample code implementation in Python v3.5.
Proxy patterns are implemented in four different ways: virtual proxy, remote proxy, protective proxy, and smart proxy. You learned about each of these with a real-world scenario.
We compared the Façade and Proxy design patterns so that the difference between their use cases and intentions are clear to you. ...
