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.
