What will I learn?
You will learn how to define and implement the Chain of Responsibility pattern using clean handler interfaces, concrete handler classes, and proper successor references. The course covers request object design, data flow management, and all three core processing strategies: pass-through, stop-and-handle, and broadcast. You will implement error handling techniques including retry logic, circuit breakers, and rollback handlers. Advanced topics include dynamic chain reconfiguration, decorator integration, distributed system design, and security handler placement. You will also develop a complete testing strategy and learn to refactor legacy conditional code into maintainable handler chains.
