fpmas::model::PointHash Struct Reference

#include <grid.h>

Public Member Functions
std::size_t	operator() (const DiscretePoint &p) const

Detailed Description

DiscretePoint hash function, inspired from boost::hash_combine.

Member Function Documentation

operator()()

std::size_t fpmas::model::PointHash::operator()

(

const DiscretePoint &

p

)

const

Computes an hash value for p using the following method:

std::size_t hash = std::hash<DiscreteCoordinate>()(p.x);
hash ^= std::hash<DiscreteCoordinate>()(p.y) + 0x9e3779b9
    + (hash << 6) + (hash >> 2);

This comes directly from the boost::hash_combine method.

Parameters

p	discrete point to hash

Returns

hash value for p
