Method Detail

startMeter

public boolean startMeter(long interval,
                          boolean dropPriorReading)

Dispatches start meter calls to all supervised meters. If even one of them fails, it immediately terminates those meters that were started before the failure.

Overrides:

startMeter in class EnergyMeter

Parameters:

interval - The meter refresh frequency.

dropPriorReading -

False: the totalConsumption values will accumulate from a previous metering session True: the totalconsumption values will start from 0 after the completion of this function.

Returns:

• False: if a metering session is already underway
• True: if the metering session was successfully initiated

stopMeter

public void stopMeter()

Dispatches stop meter calls to all supervised meters

Overrides:

stopMeter in class EnergyMeter

getTotalConsumption

public double getTotalConsumption()

Calculates the sum of total consumptions returned by each and every supervised meter

Overrides:

getTotalConsumption in class EnergyMeter

Returns:

tick

public void tick(long fires)

Specified by:

tick in class Timed
