Advantages of the Proxy Pattern

  1. Control: The Proxy Pattern allows you to control access to the real subject, enabling you to add additional features or security checks without modifying the subject itself.
  2. Lazy Loading: With virtual proxies, you can delay the creation of resource-intensive objects until they are actually needed, improving performance.
  3. Remote Access: In distributed systems, the Proxy Pattern allows you to access objects in different address spaces transparently.
  4. Security: Protection proxies can enforce access control and security checks, preventing unauthorized access to the real subject.

Proxy Pattern | C++ Design Patterns

Design Patterns are an essential part of software engineering, offering proven solutions to common problems encountered during software development. One such pattern is the Proxy Pattern. The Proxy Pattern is a structural design pattern that provides a surrogate or placeholder for another object, allowing you to control access to it. This pattern can be particularly useful in situations where you need to add an extra layer of control, lazy loading, or remote access to objects.

What is a Proxy Pattern?

The Proxy Pattern, also known as the Surrogate Pattern that falls under the Gang of Four Design Patterns, is a structural design pattern, meaning it deals with how classes and objects are composed to form larger structures. The pattern involves creating a new class (the proxy) that acts as an intermediary or placeholder for an object (the subject) to control access to it. The proxy can be a local representative of the subject, which helps in various tasks such as lazy initialization, access control, logging, monitoring, or remote communication....
