This is the specialization for SpacePoints with returning floats, where value calculates the distance...

PUT_NAME_FUNCTION(DISTANCE1DZ_NAME)
is replaced by "static const std:string name(void)" frunction which returns name of the Class
static double value(const PointType &outerHit, const PointType &innerHit)
calculates the distance between the hits in z (1D), returning unit: cm
Definition: Distance1DZ.h:31
Base class of the selection variable objects used for pair filtering.
Abstract base class for different kinds of events.
