调用

To be useful, fn should be callable .

为了有用， fn 应该是可调用的。

Factories can be methods, classes or even instances that are callable.

工厂可以是方法，类或甚至是可调用的实例。

If F is no callable, builtin type, any attempt to access the value results in a compile error.

如果 F 不是可调用内建类型，则任何访问该结果值的尝试都会引发编译错误。

We collectively refer to these types as callable builtin types.

我们将这些类型统称为可调用内建类型。

This object-oriented approach is more flexible because the callable object can keep its own state and therefore is easily extensible to other tasks.

这个面向对象的方法更灵活，因为可调用对象能保持自己的状态从而可以容易地增加新的处理工作。

Another interersting property of callable, builtin types is that they can be valid types for non-type template parameters.

可调用内建类型的另一个有趣的特性是，它们可以作为非类型模板参数的有效类型。

When a COM interface is exposed, its Runtime Callable Wrapper is used for reflection.

当一个COM接口暴露，其运行时可调用包装用于反射。

The answer is, this interface must have a special header to define it as an external method callable by the Workflow.

答案是，该接口必须有一个特殊的头定义为一个外部方法，工作流程可调用它。

If the URL is static, there is a chance that the callback will never be called.

如果URL是静态的，有一个回调将永远不会被调用的机会。

Callback function is very important in software design,its function is irreplaceable sometimes.

回调函数是软件设计中的一种非常重要的函数调用方式，在一些应用中它的作用是不可替代的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
