In this case, however, you have already modeled the IOrderManagement and callback service specifications, so you can delete the two that are created by the pattern.

然而，在这种情况下，您已经对IOrderManagement和回调服务规范建模了，因此您可以删除模式所创建的这两个内容。

So, let's create a trait that implements this pattern, then use it to handle callback behavior.

所以，让我们创建一个trait来实现这个模式，然后用它来处理回调行为。

When looking at the callback pattern from a Scala perspective what we actually see is a cumbersome implementation of a 'function'.

如果从Scala的视角来看待这种回调模式，我们发现里面充斥的全都是某个“函数”的繁琐实现。
