查询词典 iterators

In combination, these features make it easy to create iterators with no more effort than writing a regular function.

综上所述，这些功能使得编写一个正则函数成为创建迭代器的最简单方法。

For example, we could sort our vector in descending order by passing sort a pair of reverse iterators

例如，为了以降序排列 vector，只需向 sort 传递一对反向迭代器

For example, we could use iterators to print the characters of a string a line at a time to the standard output

例如，以下程序使用迭代器将一个 string 对象的字符以每次一行的方式输出到标准输出设备

Since we need to potentially merge columns from multiple SSTable versions, the reader iterators are combined through a ReducingIterator, which takes an iterator of uncombined columns as input, and yields combined versions as output

如果需要从多个SSTable版本合并列信息，那么读取迭代通过ReducingIterator进行组合，它以一组未组合过的列作为输入，以组合后的版本作为输出

For example, we could initialize an allocated but unconstructed string from a pair of iterators in either of these two ways

例如，可以用下面两种方式之一，从一对迭代器初始化一个已分配但未构造的 string 对象

Here we construct vec from a pair of iterators that denote a range of elements.

这里，用一对标记元素范围的迭代器构造 vec 对象。

But iterators are tied much more inti- mately with the actual object and will not let us play that game anymore

而迭代器是与实际对象绑定在一起的，它将不会继续执行下去

If we wish to pass a subrange, we pass iterators to the first and one past the last element of that subrange.

如果需要传递一个子区间，则传递指向这个子区间的第一个元素以及最后一个元素的下一位置的迭代器。

Because of backtracking, input iterators cannot be used.

因为要回溯，所以输入迭代器不能使用。

There are also the restrictions on when iterators can be invalidated.

在迭代器可以失效时也会有限制。

Continuously improve the production mechanism, to provide customers with better quality products and services.

不断的完善生产机制，给客户提供更优质的产品及服务。

B:Yes, he was the very prize-winner in the court tennis ten years ago?

是的，他是十年前的世界网球冠军。
