The outer function takes this timestamp and converts it to a time value.
当内部函数获得和使用其外部函数的变量时，就称其为一个闭包。
When an inner function gains and USES access to its outer function's variables it is known as a closure.

在清单2中，通过调用外部函数myfunction创建循环引用。
In Listing 2 a circular reference is created by calling the external function myFunction.
相对于静态外部函数来说，用成员函数作为事件处理器是最丑陋的做法。
And it's especially ugly if you want to use member functions as the event handlers, as opposed to static extern functions.
同样，其它对已命名对象(如模板和外部函数)的引用通常可以静态解析。
Similarly, other references to named objects such as templates and external functions can often be resolved statically.

编译器可能会作为一个调用外部函数是他们实现（大概）在标准库实现。
The compiler may implement them as a call to an external function that is (presumably) implemented in the standard library.
XQuery函数是强类型的，支持递归，可声明为内部函数或外部函数。
XQuery functions are strongly typed, support recursion, and can be declared as internal or external.
一个嵌套的内部函数可以继承外部函数的参数和变量，并由该外部函数私有。
A nested, or inner, function can inherit the arguments and variables of its outer function, and is private to that function.
由于内部函数持有到外部函数的变量的引用，所以这个带属性a的范围对象将不会被垃圾收集。
Because the inner function holds a reference to the outer function's variables, the scope object with property a will not be garbage collected.
这样的话，当外部函数返回之后，在调用内部函数时，外部函数的局部变量仍然是可用的。
Later, after the outer function has returned, when the inner function is called, the outer function's local variables will still be available to it.
如果内嵌函数只是在外部函数中使用到，那么对内嵌函数的唯一引用就是调用对象自己。
If the nested function is used only within the outer function, however, the only reference to the nested function is in the call object.
如果内嵌函数只是在外部函数中使用到，那么对内嵌函数的唯一引用就是调用对象自己。
In this case, there is an external reference to the nested function, and the nested function retains its reference to the call object of the outer function.
闭包功能非常强大，原因是它们使内部函数在外部函数返回时也仍然可以保留对此外部函数的变量的访问。
Closures are powerful because they enable inner functions to retain access to an outer function's variables even after the outer function has returned.
不管在处理对象时是否实际运行了方法，修改继承树和将对象传递给外部函数经常会使这一点变得不那么明显。
Both changed inheritance trees, and passing objects to external functions could often make it non-obvious whether a method would or would not actually run when working with an object. For example.
当用外部的x对closuredemoparentfunction进行调用时，外部函数变量a就会被赋值为外部的x。
When a call is made to closureDemoParentFunction with a parameter of outer x, the outer function variable a is assigned the value outer x.
函数s1没有在当前文件中定义，因为编译器实际上并不知道这个外部函数在哪儿，我们现在把这个符号表项保留为空白。
The function S1 is defined outside of the current file, and because the compiler doesn't actually know where the external function is, we leave this part of the symbol table blank for now.
静态vs .动态类型的讨论的评论中，Palermo提出当直接使用外部函数库的时候，动态编程就非常困难，原因是。
Commenting on a recent debate on Static vs. dynamic Typing, Palermo noted that dynamic programming is hard when it comes to use libraries because.
服务器调用一个目的函数来执行明确定义的任务，即访问和管理您的外部数据源。
The server calls a purpose function to perform well-defined tasks to access and manage your external data sources.
默认情况下，它们是由值传递的，意味着如果要更新传递到闭包函数定义内的值，则不更新外部值。
By default, they are passed by value, meaning that if we would update the value passed within the closure function definition, it would not update the outside value.
另一种方法将使用专用函数来运行外部程序。
The other method USES proprietary functions to run the external programs.
默认情况下，变量的范围是变量第一次被分配到的函数的内部，如果它的第一次分配出现在任何函数的外部，那么它就是全局变量。
By default, a variable is scoped to the function in which it is first assigned to, or is global if its first assignment occurs outside any function.
我创建了一些在插件内部调用的函数，以便插件外部的人无法调用它们。
I made the functions I call internally in the plug-in private, so that no one outside of the plug-in can call them.
并且与此类似的一个函数可以返回取决于(部分地或完全地)外部事件的连续的值。
And a function similar to this could return successive values that depend (partly or wholly) on external events.
当调用导出的键不安全的函数时，这个处理将增加相应的开销，但是仅当被调用的函数位于调用模块外部的时候才会出现这种情况。
This processing adds overhead when an exported key-unsafe function is called, but only when the called function is external to the calling module.
函数、外部例程和堆栈。
通过添加遵循特定命名约定的函数成员来响应外部事件。
Respond to external events by adding function members that follow a specified naming convention.
