An example of how to get hit id

getting_hit_id.cpp

// Get the 'calibrated_data' entry from the data model :
const snemo::datamodel::calibrated_data & the_calibrated_data
= data_record_.get<snemo::datamodel::calibrated_data>("CD");

const snemo::datamodel::calibrated_data::calorimeter_hit_collection_type & chits
= calibrated_data_.calibrated_calorimeter_hits();

for (snemo::datamodel::calibrated_data::calorimeter_hit_collection_type::const_iterator
       icalo = chits.begin(); icalo != chits.end();
     ++icalo) {
  const snemo::datamodel::calibrated_calorimeter_hit & a_calo_hit = icalo->get();
  if (a_calo_hit.has_hit_id()) {
    DT_LOG_NOTICE(datatools::logger::PRIO_NOTICE,
                  "Current calorimeter hit has " << a_calo_hit.get_hit_id() << " hit id");
  }
