Enum Constant Detail

OFF

public static final PhysicalMachine.State OFF

The machine is completely switched off, minimal consumption is recorded.

SWITCHINGON

public static final PhysicalMachine.State SWITCHINGON

The machine is under preparation to serve VMs. Some consumption is recorded already.

RUNNING

public static final PhysicalMachine.State RUNNING

The machine is currently serving VMs. The machine and its VMs are consuming energy.

SWITCHINGOFF

public static final PhysicalMachine.State SWITCHINGOFF

The machine is about to be switched off. It no longer accepts VM requests but it still consumes energy.

Method Detail

values

public static PhysicalMachine.State[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PhysicalMachine.State c : PhysicalMachine.State.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PhysicalMachine.State valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
