This variable returns the time difference among the V side clusters of the two space points.
static double value(const PointType &outerHit, const PointType &innerHit)
return the time difference (ns) among the V side clusters of the two space points

is expanded as "static const std:string name(void)" frunction which returns name of the Class
Base class of the selection variable objects used for pair filtering.
Abstract base class for different kinds of events.
