The DTrackHitSelector class is a base class for algorithms that will select hits from the drift chamber systems that are likely to belong to a specified trajectory. This class doesn't actually do the hit selection itself, it just provides a standard API so multiple algorithms can be written. It is done this way since at this point in time, we expect at least a couple of algorithms may be tried. Feb. 6, 2009 DL. More...
