问题描述
我需要递归地从目录及其子目录中获取所有文件，但不包括几个目录.我知道他们的名字.是否可以使用 boost::filesystem::recursive_directory_iterator ?
I need to recursively get all files from directory and it's subdirectory, but excluding several directory. I know their names. Is it possible to do with boost::filesystem::recursive_directory_iterator ?
推荐答案
是的，在遍历目录时，您可以测试排除列表中的名称并使用 no_push() 成员递归迭代器以防止它进入这样的目录，例如:
Yes, while iterating over directories, you can test for the names on your exclusion list and use the no_push() member of the recursive iterator to prevent it from going into such a directory, something like:
void selective_search( const path &search_here, const std::string &exclude_this_directory)
{
using namespace boost::filesystem;
recursive_directory_iterator dir( search_here), end;
while (dir != end)
{
// make sure we don't recurse into certain directories
// note: maybe check for is_directory() here as well...
if (dir->path().filename() == exclude_this_directory)
{
dir.no_push(); // don't recurse into this directory.
}
// do other stuff here.
++dir;
}
}
