Belle2::Simulation::SensitiveDetectorBase::s_mcRelations

Check if recording hits is enabled and if so call step() and set the correct MCParticle flag.

Called by Geant4 for each step inside the sensitive volumes attached

Definition at line 94 of file SensitiveDetectorBase.h.

    {
      if (!s_active) return false;
      bool result = step(aStep, aROhist);
      // Do not include hits from invalid detector (beast,teastbeam, etc.)

		RelationArray::EConsolidationAction	ignoreAction = `RelationArray::c_negativeWeight`
	)

inlinestaticinherited

Overload to make it easer to register MCParticle relations.

Parameters

relation	RelationArray to register
ignoreAction

Definition at line 66 of file SensitiveDetectorBase.h.

67 { registerMCParticleRelation(relation.getName(), ignoreAction); }

Belle2::Simulation::SensitiveDetectorBase::registerMCParticleRelation

static void registerMCParticleRelation(const std::string &name, RelationArray::EConsolidationAction ignoreAction=RelationArray::c_negativeWeight)

Register an relation involving MCParticles.

Definition: SensitiveDetectorBase.cc:22

◆ registerMCParticleRelation() [2/2]

void registerMCParticleRelation	(	const std::string &	name,
		RelationArray::EConsolidationAction	ignoreAction = `RelationArray::c_negativeWeight`
	)

staticinherited

Register an relation involving MCParticles.

All Relations which point from an MCParticle to something have to be registered with addMCParticleRelation() because the index of the MCParticles might change at the end of the event. During simulation, the TrackID should be used as index of the MCParticle

Parameters

name	Name of the relation to register
ignoreAction

Definition at line 22 of file SensitiveDetectorBase.cc.

    {
      std::pair<std::map<std::string, RelationArray::EConsolidationAction>::iterator, bool> insert = s_mcRelations.insert(std::make_pair(
            name, ignoreAction));
      //If the relation already exists and the ignoreAction is different we do have a problem
      if (!insert.second && insert.first->second != ignoreAction) {
        B2FATAL("MCParticle Relation " << name << " already registered with different ignore action.");
      }
    }

◆ setActive()

static void setActive ( bool activeStatus )

inlinestaticinherited

Enable/Disable all Sensitive Detectors.

By default, all sensitive detectors won't create hits to make it possible to use the Geant4 Navigator for non-simulation purposes. Only during simulation the sensitive detectors will be enabled to record hits

Parameters

activeStatus bool to indicate wether hits should be recorded

Definition at line 50 of file SensitiveDetectorBase.h.

50{ s_active = activeStatus; }

◆ step()

bool step	(	G4Step *	aStep,
		G4TouchableHistory *	history
	)

overridevirtual

Process each step and calculate variables defined in ECLHit.

Implements SensitiveDetectorBase.
