A basic use of a selector is for simple dispatch, which means you can dynamically reroute the destination of a service call from one component or import to another.
选择器的基本用途是进行简单的分派，这意味着您可以将服务调用的目标从一个组件或导入动态地重新路由到或导入另一个组件。
Your dependency injection would be best used on your service start-up to create handlers for each type of call, then when each call comes in, dispatch appropriately.
你的依赖注入是最好的用在你的服务启动为每个呼叫类型创建处理程序，然后在每一个电话打进来，适当派遣。
That is, a call to dispatch (foo, bar) might be a close fit with a defined rule (foo, bar) — but it might also be a loose (rather than non -) fit with (FooParent, BarParent).
也就是说，dispatch (foo,bar)调用可能是采用已定义规则(foo, bar)的较合适的分派，但是也可能与(FooParent,BarParent)规则松散(并不是不)配合。
Without needing to think about dispatch further, the multimethods.Dispatch class will select the "best fit" for a given call to a dispatcher.
无需深入研究分派， multimethods.Dispatch类将为给定分派器调用选择“最合适”的分派。
The call to the dispatcher either needs a dispatch argument, or you can use the .with_dispatch() convenience method. For example
调用分派器需要一个分派参数，或者您可以使用 .with_dispatch() 这一便利方法。
