62 // Purpose: This file contains the class definition for RectangularSeries.
63 // RectangularSeries is a concrete class. A RectangularSeries object provides
64 // a rectangular pulse time series. the factor is given by the pseudoTime and
65 // a constant factor provided in the constructor, the duration by tStart
66 // and tFinal;
67 //
68 // What: "@(#) RectangularSeries.h, revA"

double getFactor(double pseudoTime) const
Return load factor (zero if pseudoTime outside of [tStart,tFinish]).
