DomainEvent

interface DomainEvent<T : Any> : NamedMessage<DomainEvent<T>, T> , AggregateIdCapable, OwnerId, CommandId, NamedAggregate, Version, Revision

DomainEvent .

Events published when a command is processed by the aggregate

由聚合发布的领域事件 .

领域事件推荐使用声明式（Declarative）设计的方式（幂等，类似于 Kubernetes apply、Docker 镜像层）即聚合根在事件朔源时只需要简单的将领域事件作为覆盖层（onSourcing 只对状态赋值，没有逻辑判断），事件朔源将可以不需要显式定义朔源函数。
