get_neighbour()

int CaloRecGPU::NeighArr::get_neighbour ( const int cell, const int neigh_number ) const

inlineconstexpr

Definition at line 187 of file NeighArr.h.

    {
      return cells[cell][neigh_number];
    }

get_neighbours()

int CaloRecGPU::NeighArr::get_neighbours ( const unsigned int neigh_options, const int cell, int * neigh_arr ) const

inlineconstexpr

Places the neighbours according to the option(s) in neigh_options in the array and returns the number of such neighbours (not the total number of neighbours of the cell).

We're using C arrays for more immediate CUDA compatibility.
