std_cxx20::ranges::iota_view< unsigned int, unsigned int > Utilities::MPI::RemotePointEvaluation< dim, spacedim >::CellData::cell_indices | ( | ) | const |
Return an object that can be thought of as an array containing all indices from zero (inclusive) to the total number of cells where points reside given by cells.size()
(exclusive). This allows one to write code using range-based for
loops of the following kind:
Here, we are looping over all cells where points reside and use the index to call the functions get_active_cell_iterator(), get_unit_points(), and get_data_view().
