get_neighbours()

constexpr int CaloRecGPU::GeometryArr::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.
