Member Function Documentation

operator()()

template<typename T >

std::size_t std::hash< std::array< T, 3 > >::operator() ( const std::array< T, 3 > &  k ) const

inline

Calculate a hash for k.

Parameters

k	Reference to an array of coordinates (x, y, z)

Returns

The hashed value of k.

Combines the hash of x,y,and z.

// be sure to #include "meshinfo.h"
 
// Create coordinates, (x, y, z)
std::array<numeric_type, 3> arr = { 123.0, 456.1, 789.2 };
 
// Using the template specialization for std::hash (which takes a std::array<numeric_type,
// 3>), we retrieve a seed
std::size_t arr_hash = std::hash<std::array<numeric_type, 3>>(arr);
