How do I create a set with std::pair thats sorted based on the ::second pair member using bind
- by Stone Free
I know I could use the following:
template <typename Pair>
struct ComparePairThroughSecond : public std::unary_function<Pair, bool>
{
bool operator ()(const Pair& p1, const Pair& p2) const
{
return p1.second < p2.second;
}
};
std::set<std::pair<int, long>, ComparePairThroughSecond> somevar;
but wondered if it could be done with boost::bind
