Structural Design Patterns in Modern C++ - Pros and Cons - Proxy Design Pattern

The video tutorial explains the Proxy design pattern, which provides a layer of indirection to manage access to a real subject. It covers different types of proxies: virtual, protection, remote, and smart pointer. Each type serves a specific purpose, such as creating expensive objects on demand, restricting access, simplifying client implementation, and managing memory. The tutorial also discusses the advantages and disadvantages of using the proxy pattern, including its ability to add behavior at compile time and the tight coupling it creates. Guidelines for when to use the proxy pattern are provided.

What is the purpose of using a virtual proxy in the context of loading resources?

Explain how a protection proxy restricts access to a real object.

Describe the role of a remote proxy and its benefits.

What are the advantages of using smart pointers in memory management?

List some disadvantages of the proxy pattern and explain their implications.
