Member Function Documentation

◆ ProcessHits()

bool ProcessHits ( G4Step *  aStep,
G4TouchableHistory *  aROhist 
)
inlineprivatevirtualinherited

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 98 of file SensitiveDetectorBase.h.

◆ 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 70 of file SensitiveDetectorBase.h.

◆ 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 24 of file SensitiveDetectorBase.cc.

◆ 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 54 of file SensitiveDetectorBase.h.

◆ step()

bool step ( G4Step *  step,
G4TouchableHistory *   
)
overrideprotectedvirtual

Step processing method.

Parameters
stepthe G4Step with the current step information
Returns
true if a Hit has been created, false if the hit was ignored

Implements SensitiveDetectorBase.
