含义
数据总线模式(译者:实际上,就是 Event-Bus 消息总线模式)允许在一个应用程序的组件之间收发消息/事件,而不需要这些组件相互感知,它们只需要知道所发送/接收的消息/事件的类型即可。
类图
适用场景
可以在以下场景使用数据总线模式:
- 你希望由你的组件自己决定要接收哪些信息/事件
- 你希望实现多对多的通信
- 你希望你的组件不需要感知彼此
相关模式
数据总线类似于以下设计模式:
- 中介者模式(Mediator pattern),由数据总线成员自己决定是否要接受任何给定的消息。
- 观察者模式(Observer pattern),但进一步支持了多对多的通信。
- 发布/订阅模式(Publish/Subscribe pattern),但是数据总线将发布者和订阅者解耦。
