Member Function Documentation

createCoordinateMeasurement()

template<class HitType, Const::EDetector detector>

genfit::AbsMeasurement * createCoordinateMeasurement ( HitType * hit, const RecoHitInformation & recoHitInformation ) const

protectedinherited

You probably need a coordinate measurement on which you can base your measurements in createMeasurements.

This function uses the measurementFactory to create one. Please be aware that this creates two new objects on the heap: the measurement and the track point. If you do not plan to use those two in a track, please delete them! The track point can be deleted by accessing the measurements GetTrackPoints function.

Parameters

hit
recoHitInformation

Returns

a coordinate AbsMeasurement as pointer.

{
  // No one is using the trackCandHit (neither in SVDRecoHit nor in PXDRecoHit). So we do not provide any here!

                                                  nullptr);
