pattern-command

What problem does it solve?

Translates mutable operations into stand-alone command objects so callers can queue, log, and undo complex domain actions without entangling invokers in business logic.

Core Features & Use Cases

• Command interface defines a single execution entry point and optional undo helpers.
• Concrete commands capture receivers plus parameters such as entities, DTOs, or user actions.
• Invoker and receiver roles keep triggers, queues, or audit logs decoupled from the actual operation so command history can drive undo/redo or transactional outbox flows.
• Use case: wrap a reservation update request into a command for the job queue to log and reverse if needed.

Quick Start

Encapsulate the reservation update in a Command object so it can be queued, logged, and undone.
