Detailed Description

This class holds a collection of SelectionBase. It allows us to have multiple selections

Member Function Documentation

PrintStatistics()

void SelectionManager::PrintStatistics

(

)

Print #events passing cuts.

Loop over selections

Definition at line 200 of file SelectionManager.cxx.

                                       {
//********************************************************************

  /// Loop over selections
  for (std::vector<SelectionBase*>::iterator it = _eventSelections.begin(); it!=_eventSelections.end(); it++){    
    if ((*it)->IsEnabled())
      (*it)->PrintStatistics();
  }
}

ReadSelections()

void SelectionManager::ReadSelections

(

const std::string &

file

)

Read the "config" tree from the given file, to read the selections that were used when running the analysis. This is used so we can access the selections in the DrawingTools.

Definition at line 139 of file SelectionManager.cxx.

                                                          {
//********************************************************************

  // Reset the vectors
  _eventSelections.clear();

  _nMaxCuts=0;
  _nMaxBranches=0;
  _nEnabledSelections=0;

  // Read the selections from the clones array in the input file
  ReadClonesArray(file);

  for (int i=0;i<_NObjects;i++){
    SelectionBase* sel = (SelectionBase*)(*_objects)[i];    
    _eventSelections.push_back(sel);
    if (sel->IsEnabled()){

      // computes the maximum number of cuts and branches for all added selections
      if (sel->GetNBranches() >_nMaxBranches) _nMaxBranches = sel->GetNBranches();
      if (sel->GetNMaxCuts()  >_nMaxCuts)     _nMaxCuts     = sel->GetNMaxCuts();

      // recompute the number of enabled selections
      _nEnabledSelections++;
    }
  }

  //  int nselections[NMAXBRANCHES]={0};

}

SetForceFillEventSummary()

void SelectionManager::SetForceFillEventSummary

(

bool

force

)

By default EventSummary class is created and filled when the selection is passed. But this might be necessary also for events not passing the selection The user can force the EventSummary to be filled always. This function enables/disables this option for all selections in the manager

Definition at line 247 of file SelectionManager.cxx.

                                                         {
//********************************************************************

  for (std::vector<SelectionBase*>::iterator it=_eventSelections.begin();it!=_eventSelections.end();it++){
    (*it)->SetForceFillEventSummary(force);
  }  
}
