Emon and SerLCD

OK bear with me, I am at my office now so I can't test the code but I think I understand now.

Here is the code for Emonlib.h

class EnergyMonitor
{
  public:

    void voltage(int _inPinV, double _VCAL, double _PHASECAL);
    void current(int _inPinI, double _ICAL);

    void voltageTX(double _VCAL, double _PHASECAL);
    void currentTX(int _channel, double _ICAL);

    void calcVI(int wavelengths, int timeout);
    double calcIrms(int NUMBER_OF_SAMPLES);
    void serialprint();

    long readVcc();
    //Useful value variables
    double realPower,
       apparentPower,
       powerFactor,
       Vrms,
       Irms;

  private:

    //Set Voltage and current input pins
    int inPinV;
    int inPinI;
    //Calibration coeficients
    //These need to be set in order to obtain accurate results
    double VCAL;
    double ICAL;
    double PHASECAL;

    //--------------------------------------------------------------------------------------
    // Variable declaration for emon_calc procedure
    //--------------------------------------------------------------------------------------
	int lastSampleV,sampleV;   //sample_ holds the raw analog read value, lastSample_ holds the last sample
	int lastSampleI,sampleI;                      

	double lastFilteredV,filteredV;                   //Filtered_ is the raw analog value minus the DC offset
	double lastFilteredI, filteredI;                  

	double phaseShiftedV;                             //Holds the calibrated phase shifted voltage.

	double sqV,sumV,sqI,sumI,instP,sumP;              //sq = squared, sum = Sum, inst = instantaneous

	int startV;                                       //Instantaneous voltage at start of sample window.

	boolean lastVCross, checkVCross;                  //Used to measure number of times threshold is crossed.
	int crossCount;                                   // ''


};

In the original sketch there is a piece of code:
emon1.calcVI(20,2000);

It looks to me this is a reference to the code below:

void calcVI(int wavelengths, int timeout);

I guess this part means I should be able to call it in a sketch right?
double realPower,
** apparentPower,**
** powerFactor,**
** Vrms,**
** Irms;**

using:
emon1.realPower
emon1.apparentPower
emon1.powerFactor
emon1.Vrms
emon1.Irms

Is this correct or not?
