你怎么称呼它，当一个接口"继承"从另一个？ [英] What do you call it when one interface "inherits" from another?

问题描述

如果我有
B类：A {}

If I have class B : A {}

我说，B级的继承的A级或

I say that "Class B inherited class A" or "class B derives from class A".

However, if I instead have:

不过，如果我不是有C $ C> b类：ISomeInterface {}

class B : ISomeInterface {}

这是错误的说法b继承ISomeInterface - 适当的期限是说b的工具的ISomeInterface。

it's wrong to say "B inherits ISomeInterface" -- the proper term is to say "B implements ISomeInterface".

不过，说我有

  interface ISomeInterface : ISomeOtherInterface   {}

现在，它仍然是错误的说法继承，但它现在只是因为错误的说工具，因为ISomeInterface没有实现任何东西。

Now, it's still wrong to say "inherits", but it's now just as wrong to say "implements" since ISomeInterface doesn't implement anything.

那么，你叫什么了关系？

So, what do you call that relationship?

推荐答案

我个人说：伸出我的认为的C＃的规范使用这个词作为还有的地方（我现在不能找到它，可惜） - 但我记得埃里克利珀说他并不热衷于它，并想改变它的4.0

I personally say "extends" and I thought the C# spec uses that word as well somewhere (I can't find it now, unfortunately) - but I remember Eric Lippert saying he wasn't keen on it, and wanted to change it for 4.0.

我认为这是很好的，因为它表明你是通过延长原有接口指定的合约

I think it's good, because it shows that you're extending the contract specified by the original interface.

编辑：说完看了看3.0规范...

Having looked at the 3.0 spec...

该规范排序在第13.2侧步的问题。它谈论的成员正在从基接口继承。它谈论有一个类的另一种延伸，而不是接口

The spec sort of side-steps the issue in section 13.2. It talks about the members being inherited from the base interfaces. It talks about one class extending another, but not interfaces

编辑：在C＃5规范，13.1.4节，它采用继承：

In the C# 5 spec, section 13.1.4, it uses inherits:

这是接口可以从零个或多个接口类型继承

An interface can inherit from zero or more interface types

所以，这可能是使用最好的词。

So that's probably the best term to use.
