Boost Filesystem Directory_iterator的非确定性执行

以下代码在给定的目录上递归迭代，并每次以相同的顺序打印其内容。

是否可以更改目录迭代器以随机打印目录内容（即不使用矢量来存储结果，然后随机打印向量内容）？

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
int main(int argc, char** argv)
{
  boost::filesystem::path dataPath("/home/test/");
  boost::filesystem::recursive_directory_iterator endIterator;
  // Traverse the filesystem and retrieve the name of each root object found
  if (boost::filesystem::exists(dataPath) && boost::filesystem::is_directory(dataPath)) {
    for (static boost::filesystem::recursive_directory_iterator directoryIterator(dataPath); directoryIterator != endIterator;
     ++directoryIterator) {
      if (boost::filesystem::is_regular_file(directoryIterator->status())) {
        std::string str = directoryIterator->path().string();
        cout << str << endl;
        }
    }
}

}
