Class Energy

java.lang.Object
  avrora.sim.Energy

public class Energy

extends java.lang.Object

Class for energy modeling. All consumers create an instance of this class and keep it updated with all state changes concerning power consumption. This class keeps track of all these state changes and cycles spend in each state. The state changes are propagated to monitors based on a subscription system. This enables logging of power consumption.

Constructor Summary

Energy(java.lang.String deviceName, double[] modeAmphere, java.lang.String[] modeName, int cpuFreq, int startMode, EnergyControl ec, State st)
create new energy class, to enable energy modelling

Method Summary

double	getConsumedEnergy(int mode) get the power consumption of a state
double	getCurrentAmphere() get the current draw
int	getCurrentMode() get the current state or mode of the device
long	getCycles(int mode) get the cycles spend in a device state
double	getModeAmphere(int mode) get the current draw of a mode
java.lang.String	getModeName(int mode) get the name of a mode
java.lang.String[]	getModeNames() get the names of all modes
int	getModeNumber() get the number of modes of this device
java.lang.String	getName() get the device name
double	getOldAmphere() get the current draw of the old mode
int	getOldMode() get old mode
double	getTotalConsumedEnergy() get the power consumption of this device
void	setMode(int mode) set the current mode or state of the device
