Enum Constant Detail

REQUESTED

public static final MachineState REQUESTED

The machine has been requested from the underlying infrastructure and the request is pending fulfillment.

REJECTED

public static final MachineState REJECTED

The machine request was rejected by the underlying infrastructure.

PENDING

public static final MachineState PENDING

The machine is in the process of being launched.

RUNNING

public static final MachineState RUNNING

The machine is launched. However, the boot process may not yet have completed and the machine may not be operational (the Machine's ServiceState may provide more detailed state information).

TERMINATING

public static final MachineState TERMINATING

The machine is in the process of being stopped/shut down.

TERMINATED

public static final MachineState TERMINATED

The machine has been stopped/shut down.

Method Detail

values

public static MachineState[] 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 (MachineState c : MachineState.values())
    System.out.println(c);

Returns:

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

valueOf

public static MachineState 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
