NONE

public static final IAgent.State NONE

The state of an agent that has not been initialized yet.

INIT

public static final IAgent.State INIT

The state of an initialized agent. It has not been started yet.

STARTED

public static final IAgent.State STARTED

The state of a started agent. It is currently active and performing its work.

PAUSED

public static final IAgent.State PAUSED

The state of a paused agent. Its active status has been temporarily suspended, and it won't be performing its work until it is resumed.

STOPPED

public static final IAgent.State STOPPED

The state of a stopped agent. A stopped agent is "shut down". It won't perform any work anymore and cannot be re-started.

Method Detail

values

public static IAgent.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 (IAgent.State c : IAgent.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 IAgent.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
