CXXGRAPH::pair_hash Struct Reference

#include <Typedef.hpp>

Public Member Functions
template<class T1 , class T2 >
std::size_t	operator() (const std::pair< T1, T2 > &p) const

Detailed Description

The C++ Standard doesn't provide a hash for std::pair type, which is required when using std::pair as a key in std::unordered_map. So, hash function for pair needs to be provided. Hash for a pair is calculated by calcuating hash for individual elements and then combining. For combining, an implmentation similar to boost hash_combine is implemented.
