如何迭代提升属性树?
我知道正在接近 boost 属性树,并看到它是用于 c++ 编程的 boost 库的一个很好的特性.
I am know approaching to boost property tree and saw that it is a good feature of boost libs for c++ programming.
嗯,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?
在参考中只是一个浏览树的例子:
In reference there is just an example of browsing the tree through:
BOOST_FOREACH
但是没有别的了吗?类似于 stl 的容器之类的东西?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只是一种方便的迭代方式,可以通过iterator、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)
...
从 C++11 开始就是:
And since C++11 it's:
for (auto& it: tree)
...
