class ring::NeighBond

Membership of the neighbour rows after the leading self entry. Built once per frame so the basal test does not scan those rows.

#include <src/include/internal/topo_bulk.hpp>
 
class NeighBond {
public:
    // methods
 
    void build(const std::vector<std::vector<int>>& nList);
    bool operator()(int i, int j) const;
};
