◆ registerMCParticleRelation() [1/2]

static void registerMCParticleRelation ( const RelationArray relation,
RelationArray::EConsolidationAction  ignoreAction = RelationArray::c_negativeWeight 
)
inlinestaticinherited

Overload to make it easer to register MCParticle relations.

Parameters
relationRelationArray to register
ignoreAction

Definition at line 66 of file SensitiveDetectorBase.h.

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

◆ 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
nameName of the relation to register
ignoreAction

Definition at line 22 of file SensitiveDetectorBase.cc.

23 {
24 std::pair<std::map<std::string, RelationArray::EConsolidationAction>::iterator, bool> insert = s_mcRelations.insert(std::make_pair(
25 name, ignoreAction));
26 //If the relation already exists and the ignoreAction is different we do have a problem
27 if (!insert.second && insert.first->second != ignoreAction) {
28 B2FATAL("MCParticle Relation " << name << " already registered with different ignore action.");
29 }
30 }

◆ 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
activeStatusbool 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 *   
)
overridevirtual

Process each step and calculate variables defined in PXDSimHit.

Parameters
aStepCurrent Geant4 step in the sensitive medium.
Returns
true if a hit was stored, o.w. false.

Implements SensitiveDetectorBase.
