Detailed Description

template<class T1, class T2>
struct theplu::yat::utility::pair_value_compare< T1, T2 >

Functor comparing pairs using second.

STL provides operator< for the pair.first element, but none for pair.second. This template provides this and can be used as the comparison object in generic functions such as the STL sort.
