The Proxy Design Pattern is a structural design pattern that provides a surrogate or placeholder for another object to control access to it. This pattern is useful when you want to add an extra layer of control over access to an object. The proxy acts as an intermediary, controlling access to the real object1.
Components of Proxy Design Pattern
Subject: An interface or abstract class that defines the common interface shared by the RealSubject and Proxy classes. It declares the methods that the Proxy uses to control access to the RealSubject1.
RealSubject: The actual object that the Proxy represents. It contains the real implementation of the business logic or the resource that the client code wants to access1.
Proxy: Acts as a surrogate or placeholder for the RealSubject. It controls access to the real object and may provide additional functionality such as lazy loading, access control, or logging1.

Proxy pattern - Wikipedia
In computer programming, the proxy pattern is a software design pattern. A proxy, in its most general form, is a class functioning as an interface to something else. The proxy could interface to anything: a network connection, a large object in memory, a file, or some other resource that is expensive or impossible to duplicate. In short, a proxy is a wrapper or agent object that is being called by the client to access the real serving object behind the scenes. Use of the proxy can si…
