Detailed Description

template<class HitType, Const::EDetector detector>
class Belle2::BaseMeasurementCreatorFromHit< HitType, detector >

Base Class to create measurements based on a given hit related to the RecoTrack.

Use this class as a base class if you want to add TrackPoints with measurements that are created for each svd/pxd/cdc hit. If you do not relate to a specific hit from the track finders (for example for ECL energy measurements as a TrackPoint) you should not use this class as a base class but rather use BaseMeasurementCreator directly.

TODO: It would be better to skip the genfit::MeasurementFactory completely and just implement the conversion here directly!

Member Function Documentation

◆ createCoordinateMeasurement()

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

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.

const std::string &  parameterValue 
)

Use this to set the parameters of the creator.

Does nothing per default.
