Class HelicalTrackHitDriver

org.lcsim.util.Driver

org.lcsim.fit.helicaltrack.HelicalTrackHitDriver

public class HelicalTrackHitDriver
extends Driver

Create the appropriate HelicalTrackHits for the specified TrackerHit collections. The resulting HelicalTrackHits encapsulate the information needed to perform a helical track hit for either a segmented strip detector, a pixel detector, or cross hits from a stereo detector. At this time, this driver supports the virtual segmentation hits produced by the packages in contrib.onoprien.tracking. Additional coding needs to be done to support fully segmented detectors. The list of hit collections to be converted must be specified before the process method is executed. Currently,
