Detailed Description

Implementation of a calculator used in the SoftwareTriggerModule to fill a SoftwareTriggerObject for doing HLT prefilter cuts.

This calculator exports variables needed for the trigger HLT prefilter part of the path ( = filtering out injection background events)

This class implements the two main functions requireStoreArrays and doCalculation of the SoftwareTriggerCalculation class.

Member Function Documentation

addDebugOutput()

void addDebugOutput ( const StoreObjPtr< SoftwareTriggerVariables > & storeObject, const std::string & prefix )

inherited

Function to write out debug output into the given StoreObject.

Needs an already prefilled calculationResult for this (probably using the fillInCalculations function). All added variables are prefixed with the given prefix string.

Definition at line 34 of file SoftwareTriggerCalculation.cc.

    {
      for (const auto& identifierWithValue : m_calculationResult) {
        const std::string& identifier = identifierWithValue.first;
        const double value = identifierWithValue.second;
 
        storeObject->append(prefix + "_" + identifier, value);
      }
    }

doCalculation()

void doCalculation ( SoftwareTriggerObject & calculationResult )

overridevirtual

Actually write out the variables into the map.

< Events with high SVD-CDC occupancy

< Events in the injection strip

Implements SoftwareTriggerCalculation.

Definition at line 22 of file PrefilterCalculator.cc.

{
  //..Filters lines for HLTPrefilter decision
  calculationResult["EventsOfDoom"] = 0; 
  calculationResult["InjectionStrip"] = 0; 
 
  // EventsOfDoomBuster mode decision
  if (m_eodbPrefilter.computeDecision()) {
    calculationResult["EventsOfDoom"] = 1;
  }
  // Injection time mode decision
  if (m_timingPrefilter.computeDecision()) {
    calculationResult["InjectionStrip"] = 1;
  }
 
}

fillInCalculations()

const SoftwareTriggerObject & fillInCalculations ( )

inherited

Main function of this class: calculate the needed variables using the overwritten doCalculation function and write out the values into the results object (with their names).

Please make sure to override (or clear) the variables! Otherwise it can happen that their old values are still in the object.

What variables exactly are added to the result depends on the implementation details of the class.

Definition at line 44 of file SoftwareTriggerCalculation.cc.

    {
      const unsigned int sizeBeforeCheck = m_calculationResult.size();
      doCalculation(m_calculationResult);
 
      if (m_calculationResult.size() != sizeBeforeCheck and sizeBeforeCheck > 0) {
        B2WARNING("Calculator added more variables (" << m_calculationResult.size() <<
                  ") than there were before (" << sizeBeforeCheck << "). Probably something strange is going on!");
      }
 
      return m_calculationResult;
    }

requireStoreArrays()

void requireStoreArrays ( )

overridevirtual

Require the particle list. We do not need more here.

Implements SoftwareTriggerCalculation.

}

writeDebugOutput()

void writeDebugOutput ( const std::unique_ptr< TTree > & debugOutputTTree )

inherited

Function to write out debug output into the given TTree.

Needs an already prefilled calculationResult for this (probably using the fillInCalculations function).

Definition at line 19 of file SoftwareTriggerCalculation.cc.

    {
      if (not m_debugPrepared) {
        for (auto& identifierWithValue : m_calculationResult) {
          const std::string& identifier = identifierWithValue.first;
          double& value = identifierWithValue.second;
 
          debugOutputTTree->Branch(identifier.c_str(), &value);
        }
        m_debugPrepared = true;
      }
 
      debugOutputTTree->Fill();
    }
