Detailed Description

Functor applying the proper referenced_address() function.

referenced_address()

This class operates in the same way as util::referenced_address(), but it is easier to use in STL algorithms since it's not a template:

std::vector<int> data(4U, 0);
std::vector<int const*> dataPtr;
std::transform(data.cbegin(), data.cend(), std::back_inserter(dataPtr),
  util::reference_addresser());

will fill dataPtr with the pointers to the elements in data. This is easier than taking the address of the correct template instance of util::referenced_address(), or than writing a lambda function for that.
