37 // Class description:
38 //
39 // Defines the EventAction used during tracing of magnetic field
40 // lines. During the EndOfEventAction() it stores magneticfield lines
41 // as polyline and polymarker objects.
42 // These polyline and polymarker objects can be drawn by using the
43 // DrawFieldLines() method.
