Use Cases of the Proxy Pattern
The Proxy Pattern is particularly useful in various scenarios:
- Lazy Loading: When you have a resource-intensive object that should be loaded only when it is needed, a proxy can handle its creation. For instance, loading large images or database connections on-demand.
- Access Control: Proxies can control access to the Real Subject by adding authentication and authorization checks. This is especially useful in securing sensitive resources.
- Caching: Proxies can cache the results of expensive operations, reducing the need to invoke the Real Subject repeatedly.
- Logging and Monitoring: Proxies can be used to log or monitor the actions performed on the Real Subject without modifying its code.
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.
