Interface PowerHost

All Superinterfaces:

ChangeableId, Comparable<Host>, Host, HostDynamicWorkload, Identificable, Machine, Resourceful

All Known Implementing Classes:

PowerHostSimple, PowerHostUtilizationHistory

public interface PowerHost
extends HostDynamicWorkload

An interface to be implemented by power-aware Host classes. The interface implements the Null Object Design Pattern in order to start avoiding NullPointerException when using the NULL object instead of attributing null to PowerHost variables.

Since:

CloudSim Plus 1.0

Field Detail

NULL

static final PowerHost NULL

An attribute that implements the Null Object Design Pattern for PowerHost objects.

Method Detail

getEnergyLinearInterpolation

double getEnergyLinearInterpolation(double fromUtilization,
                                    double toUtilization,
                                    double time)

Gets the energy consumption using linear interpolation of the utilization change.

Parameters:

fromUtilization - the initial utilization percentage

toUtilization - the final utilization percentage

time - the time

Returns:

the energy

getMaxPower

double getMaxPower()

Gets the max power that can be consumed by the host.

Returns:

the max power

getPower

double getPower()

Gets the power consumption of the host. For this moment it only computes the power consumed by PEs.

Returns:

the power consumption

getPowerModel

PowerModel getPowerModel()

Gets the power model.

Returns:

the power model

setPowerModel

PowerHost setPowerModel(PowerModel powerModel)

Sets the power model.

Parameters:

powerModel - the new power model

Returns:
