- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `ACCESS_DENIED` Returned when requesting a role in a secured group fails
    `AGENT_CRASH` Returned by launch primitives when the launched agent crashes in activate
    `ALREADY_GROUP` Returned when using `AbstractAgent.createGroup(String, String, boolean, Gatekeeper)` and that a group already exists
    `ALREADY_KILLED` Returned by kill primitives when the targeted agent is already terminated
    `ALREADY_LAUNCHED` Returned when launching an agent which is already launched
    `CANT_REPLY` Returned when an agent tries to reply to a message which has not been received from another agent, e.g. newly created or sent directly by an object using `AbstractAgent.receiveMessage(Message)`.
    `IGNORED` Returned when `AbstractAgent.requestRole(String, String, String, Object)` or `AbstractAgent.createGroup(String, String, boolean, Gatekeeper)` is used in activate and that the agent has been launched using `AbstractAgent.launchAgentBucket(List, String...)` or `AbstractAgent.launchAgentBucket(String, int, String...)`
    `INVALID_AGENT_ADDRESS` Returned by send primitives when the targeted agent address does not exist anymore, i.e. the related agent has leaved the corresponding role
    `NO_RECIPIENT_FOUND` Returned by send primitives when the targeted CGR location does not exist or contain any agent
    `NOT_COMMUNITY` Indicates that a community does not exist
    `NOT_GROUP` Indicates that a group does not exist
    `NOT_IN_GROUP` Indicates that the agent is not in a group
    `NOT_ROLE` Indicates that a role does not exist
    `NOT_YET_LAUNCHED` Returned by kill primitives when the targeted agent has not been launched priorly
    `ROLE_ALREADY_HANDLED` Returned when the agent already has the requested role
    `ROLE_NOT_HANDLED` Returned when the agent does not have a role that it is supposed to have doing a particular action, e.g.
    `SEVERE` Returned on special errors.
    `SUCCESS`
    `TIMEOUT` Returned by various timed primitives of the Agent class like `Agent.sendMessageAndWaitForReply(AgentAddress, Message)` or `AbstractAgent.launchAgent(AbstractAgent, int, boolean)`

- ### Method Detail

  - #### values

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

  - #### valueOf

        public static AbstractAgent.ReturnCode 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

  - #### toString

        public String toString()

    Overrides:
      `toString` in class `Enum<AbstractAgent.ReturnCode>`
