Class Acts::DD4hepVolumeBuilder

class DD4hepVolumeBuilder : public Acts::IConfinedTrackingVolumeBuilder

build confined TrackingVolumes of one cylinder setup from DD4hep input.

This class is an implementation of the Acts::IConfinedTrackingVolumeBuilder, creating the central (volumes of barrel), the negative and positive volumes (volumes of endcaps) of one hierarchy (e.g. ECal, HCal…) with input from DD4hep.
