Member Function Documentation

initMapKeys()

template<typename T >

void tauRecTools::TauDecayModeNNHelper::initMapKeys ( std::map< std::string, T > &  empty_map, const std::set< std::string > &  keys  )

static

initialise the map with a set of defined keys

Parameters

empty_map	the map to be initialised
keys	a set that contains the keys for the map

the template type can be any type the map does not necessary need to be empty

Definition at line 418 of file TauDecayModeNNClassifier.cxx.

  {
    // T can be any type
    for (const auto &key : keys)
    {
      empty_map[key];
    }
  }

Log10Robust()

float tauRecTools::TauDecayModeNNHelper::Log10Robust ( const float  val, const float  min_val = 0.  )

static

Definition at line 401 of file TauDecayModeNNClassifier.cxx.

  {
    return TMath::Log10(std::max(val, min_val));
  }

sortAndKeep()

template<typename T >

void tauRecTools::TauDecayModeNNHelper::sortAndKeep ( std::vector< T > &  vec, const std::size_t  n_obj  )

static

sort the objects and only keep the leading N objects in the vector

Parameters

vec	a vector of physics object pointers
n_obj	number of leading pT objects to keep

the template type must have pt() method (e.g. PFO*, TauTrack*) objects are sorted by pT in descending order the redundant objects will not be used

Definition at line 407 of file TauDecayModeNNClassifier.cxx.

  {
    auto cmp_pt = [](const T lhs, const T rhs) { return lhs->pt() > rhs->pt(); };
    std::sort(vec.begin(), vec.end(), cmp_pt);
    if (vec.size() > n_obj)
    {
      vec.erase(vec.begin() + n_obj, vec.end());
    }
  }
