如何迭代boost属性树？ [英] How to iterate a boost property tree?

问题描述

我知道接近提升属性树，并看到它是一个很好的功能的boost libs c ++编程。

I am know approaching to boost property tree and saw that it is a good feature of boost libs for c++ programming.

好，我有一个疑问？如何使用迭代器或类似方法迭代属性树？

Well, I have one doubt? how to iterate a property tree using iterators or similar?

在引用中，只是一个浏览树的示例：

In reference there is just an example of browsing the tree through:

BOOST_FOREACH

像stl一样的容器吗？这将是一个更好的解决方案，谈到代码质量....

But is there nothing more? Something like an stl-like container? It would be a better solution, speaking about code quality....

推荐答案

BOOST_FOREACH只是一个方便的迭代方法可以通过迭代器begin（）和end（）来完成。

BOOST_FOREACH is just a convenient way for iterating that can be done by iterator, begin() and end()

Your_tree_type::const_iterator end = tree.end();
for (your_tree_type::const_iterator it = tree.begin(); it != end; ++it)
    ...

在C ++ 11中：

for (auto it: tree)
    ...
