SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Proxy Pattern provides a surrogate for a real subject to control access and behavior, enabling security, lazy loading, remote interaction, and monitoring.

Core Features & Use Cases

  • Lazy loading: delays heavy object creation until first use.
  • Access control: enforces permissions before forwarding requests.
  • Remote/proxy access: enables distributed or remote object access.
  • Logging and monitoring: observes calls for auditing and performance.

Quick Start

Create a proxy around your real object and invoke methods to observe lazy loading and access control in action.

FAQPage Schema
What is the proxy pattern used for in software engineering?

The proxy pattern provides a surrogate to control access to a real subject, enabling security, lazy loading, remote interaction, and monitoring across software systems.

How do I implement lazy loading for heavy objects in my application?

Create a proxy around your real object to delay heavy object creation until first use, invoking methods to observe lazy loading and access control in action.

Can I enforce access control checks before forwarding requests to an object?

Yes, access control is a core feature of the proxy pattern, enforcing permissions before forwarding requests to the real subject through a forwarding mechanism.

Does the proxy pattern support logging and monitoring for auditing?

Yes, the proxy pattern observes calls for auditing and performance monitoring, applying monitoring hooks to log interactions with the real subject.

When should I use a remote proxy for distributed object access?

Use a remote proxy when you need remote access and distributed object interaction, enabling a surrogate to forward requests across software systems.

What are the limitations of using a proxy pattern for access control?

The proxy pattern requires a forwarding mechanism to the real object, adding optional components like lazy initialization and access control checks that may introduce overhead.
