It acts as an intermediary or a representative, allowing you to add an extra layer of control, security, or functionality to the original object without modifying its core behavior. The Proxy pattern is commonly used in various scenarios to manage access to resources, optimize performance, or implement lazy loading.Why do we use a Proxy Class?Proxy classes are used in software development for various reasons, primarily to add an additional layer of control, security, or functionality to objects or services without modifying their core behavior. Here are some common reasons why we use proxy classes:What kind of problems does proxy pattern solve?Let us try understanding a specific usecase of OrderFulfillmentService where a Virtual Proxy is used that delays the instantiation of the real service until it’s actually needed.In this example:This example demonstrates the concept of a virtual proxy by delaying the creation of the real service until it’s required, optimizing resource usage.Overall, the Proxy pattern enhances control, security, and performance while maintaining a consistent interface for clients. It is widely used in various software applications to manage and optimize interactions with real objects or services, making it a valuable design pattern in software development.References:en.wikipedia.org----Level Up CodingSoftware Engineer with expertise in building scalable products.
