Description: The Virtual Proxy is a design pattern that acts as a placeholder for another object to control access to it. This pattern is particularly useful in situations where the creation of a real object is resource-intensive, whether due to heavy memory usage, processing time, or the need for network operations. By using a virtual proxy, the creation of the real object can be delayed until it is absolutely necessary, thus optimizing performance and system efficiency. Additionally, the proxy can implement additional logic, such as permission management, lazy data loading, or caching, allowing for more granular control over how and when the real object is accessed. This pattern is common in applications that require efficient resource management, such as in various software development contexts, web applications, and distributed systems, where latency and resource usage are critical considerations. In summary, the Virtual Proxy not only acts as an intermediary but can also enrich the functionality of the object it represents, enhancing user experience and overall system efficiency.
