It will list all the networks, interfaces, devices.

这会列出所有网络、接口和设备。

However, there is not an option to check if objects implement the interfaces they claim to implement, and there is no way of introspecting an object to list the interfaces it supports.

不过，没有选项来检查对象是否实现了它们所声明的接口，而且也没有办法可以调查对象内部以使列出其支持的接口。

So it's optional whether the less-derived implemented interfaces are stated in the base type list?

那么就是说派生程度较低的接口是否被声明在基类列表中是可选的了？
