[Boost-users] I search information about directory_iterator

Subject: [Boost-users] I search information about directory_iterator

I have:
#include <boost/filesystem.hpp>
namespace fs=boost::filesystem;

for (auto& de : fs::directory_iterator("D:\\prog\\alg\\Diff"))
{
    fs::path p = de.path();
    auto ext = fs::extension(p);
}

directory_iterator is object or non-objective method?
How can I write something similar, but database iterator.
I want get information from mySQL. The simplest way is add everything
returning by select to vector of vector of string.
But I prefer database iterator. How it write? How is in general
directory_iterator as a iterator model?
