// Step 1: Define an interface interface PaymentProcessor Result process(Transaction t);

// Step 3: Using Reflect4 to build a "top" proxy ProxyConfig config = new ProxyConfig() .setInterceptor(new LoggingInterceptor()) .setInterceptor(new RateLimitInterceptor()) .setTopology(Topology.HIERARCHICAL); made with reflect4 proxy top

// Step 4: Client code calls the proxy proxy.process(tx); // Behind the scenes: // 1. Reflect4 proxy intercepts call. // 2. Logs input parameters. // 3. Checks rate limits. // 4. Delegates to StripeProcessor. // 5. Logs result. // 6. Returns. // Step 1: Define an interface interface PaymentProcessor

However, for simple CRUD apps or static websites, this pattern is overkill. Use it where complexity demands dynamism: API gateways, middleware platforms, testing mocks, and multi-tenant SaaS backends. made with reflect4 proxy top

// Step 2: Real implementation class StripeProcessor implements PaymentProcessor Result process(Transaction t) /* charge card */
