转换std :: vector的绝佳解决方案 <boost::shared_ptr<T> &gt;进入std :: vector <T*>

Question

I did not find exactly the same question.

Is there a way to convert a:

std::vector<boost::shared_ptr<T>>

into a non safe version:

std::vector<T*>

without doing a for loop and using .get() on each element of the original vector ?

Answer 1

std::transform(safe.begin(), safe.end(), std::back_inserter(unsafe),
               boost::bind(&boost::shared_ptr<T>::get, _1));
