```
The super class of all MaDKit agents, v 5. It provides support for
- Agent's Life cycle, logging, and naming.
- Agent launching and killing.
- Artificial society creation and management.
- Messaging.
- Minimal graphical interface management.
The agent's behavior is intentionally not defined. It is up to the agent developer to choose an agent model or to develop his specific agent library on top of the facilities provided by the MaDKit API. However, all the launched agents share the same organizational view, and the basic messaging code, so integration of different agents is quite easy, even when they are coming from different developers or have heterogeneous models.
Agent-related methods (most of this API) is only effective after the agent has been launched and thus registered in the current Madkit session. Especially, that means that most of the API has no effect in the constructor method of an Agent and will only produce a warning if used.

MaDKit v.5 new features
- One of the big change that comes with version 5 is how agents are identified and localized within the artificial society. An agent is no longer binded to a single agent address but has as many agent addresses as holden positions in the artificial society. see AgentAddress for more information.
- With respect to the previous change, a withRole version of all the messaging methods has been added. See sendMessageWithRole(AgentAddress, Message, String) for an example of such a method.
- A replying mechanism has been introduced through SendReply methods. It enables the agent with the possibility of replying directly to a given message. Also, it is now possible to get the reply to a message, or to wait for a reply ( for Agent subclasses only as they are threaded) See sendReply(Message, Message) for more details.
- Agents now have a formal state during a MaDKit session. See the getState() method for detailed information.
- One of the most convenient improvement of v.5 is the logging mechanism which is provided. See the getLogger() method for more details.

Method Detail

getSimulationTime
```
public Scheduler.SimulationTime getSimulationTime()
```
Returns the Scheduler.SimulationTime of the current simulation. This is automatically initialized when the agent is associated with an activator for the first time. So it stays null if the agent is not related to a simulation

Returns:

the simulationTime of the simulation in which the agent participates

getNextEventDate
```
public LocalDateTime getNextEventDate()
```
Method which is used by discrete-event simulation activators for doing fine-grained simulations. By default, this method returns an event which is one second ahead of the current date of the simulation. So, this method can be overridden to fulfil the simulation requirement

Returns:

the date of the next event for this agent.

See Also:

DiscreteEventAgentsActivator, DateBasedDiscreteEventActivator

createGUIOnStartUp
```
public void createGUIOnStartUp()
```
Activates the MaDKit GUI initialization when launching the agent whatever the launching parameters. By default agents are launched without a GUI but some of them always need one: This ensures that the agent will have one. This method should be used only in the constructor of the agent, otherwise it will be useless as it specifies a boot property of the agent.

hasGUI
```
public boolean hasGUI()
```
Tells if this agent has a GUI automatically built by the kernel

Returns:

true if this agent has a GUI built by the kernel

hashCode
```
public final int hashCode()
```
The ID of an agent. All the agents have different hashCode value in one kernel. Thus it can be used to identify one agent. In a networked environment, this value should be used in combination with the kernelAddress of the agent for unique identification. This also holds when multiple MaDKit kernels are launched within the same JVM.

Overrides:

hashCode in class Object

Returns:

the agent's unique ID in the MaDKit kernel

getNetworkID
```
public final String getNetworkID()
```
Return a string representing a unique identifier for the agent over the network.

Returns:

the agent's network identifier

getSimpleNetworkID
```
public final String getSimpleNetworkID()
```
Return a string representing a shorter version of the unique identifier of the agent over the network. As a simplified version, this string may not be unique.

Returns:

a simplified version of the agent's network identifier

See Also:

getNetworkID()

isAlive
```
public boolean isAlive()
```
Returns true if the agent has been launched and is not ended nor killed.

activate

protected void activate()

This method corresponds to the first behavior which is called by the MaDKit kernel when an agent is launched. Usually a good place to take a position in the organization of the artificial society.

Here is a typical example:

 @Override
 protected void activate()
 {
        AbstractAgent.ReturnCode returnCode = requestRole("a community", "a group", "my role");
        if (returnCode == AbstractAgent.ReturnCode.SUCCESS){
                if(logger != null)
                        logger.info("I am now playing my role in the artificial society");
        }
        else{
                if(logger != null)
                        logger.warning("something wrong, return code is "+returnCode);
        }
 }

end

protected void end()

This method corresponds to the last behavior which is called by the MaDKit kernel. This call occurs when a threaded agent normally exits its live method or when the agent is killed. Usually a good place to release taken resources or log what has to be logged. It has to be noted that the kernel automatically takes care of removing the agent from the organizations it is in. However, this cleaning is not logged by the agent. Therefore it could be of interest for the agent to do that itself.

Here is a typical example:

 @Override
 protected void end()
 {
        AbstractAgent.ReturnCode returnCode = leaveRole("a community", "a group", "my role");
        if (returnCode == AbstractAgent.ReturnCode.SUCCESS){
                if(logger != null)
                        logger.info("I am leaving the artificial society");
        }
        else{
                if(logger != null)
                        logger.warning("something wrong when ending, return code is "+returnCode);
        }
        if(logger != null)
                logger.info("I am done");
        }
 }

launchAgent
```
public AbstractAgent.ReturnCode launchAgent(AbstractAgent agent)
```
Launches a new agent in the MaDKit platform. This has the same effect as launchAgent(agent,Integer.MAX_VALUE,false)
Parameters:

agent - the agent to launch.

Returns:
- AbstractAgent.ReturnCode.SUCCESS : The launch has succeeded. This also means that the agent has successfully completed its activate method
- AbstractAgent.ReturnCode.ALREADY_LAUNCHED : If this agent has been already launched
- AbstractAgent.ReturnCode.TIMEOUT : If your agent is activating for more than 68 years Oo !
- AbstractAgent.ReturnCode.AGENT_CRASH : If the agent crashed during its activate method
Since:

public AbstractAgent.ReturnCode launchAgent(AbstractAgent agent,
                                            int timeOutSeconds)
```
Launches a new agent in the MaDKit platform. This has the same effect as launchAgent(agent,timeOutSeconds,false)
Parameters:

agent - the agent to launch.

timeOutSeconds - time to wait the end of the agent's activation until returning a TIMEOUT.

Returns:
- AbstractAgent.ReturnCode.SUCCESS : The launch has succeeded. This also means that the agent has successfully completed its activate method
- AbstractAgent.ReturnCode.ALREADY_LAUNCHED : If this agent has been already launched
- AbstractAgent.ReturnCode.TIMEOUT : If the activation time of the agent is greater than timeOutSeconds seconds

                                            boolean createFrame)
```
Launches a new agent in the MaDKit platform. This has the same effect as launchAgent(agent,Integer.MAX_VALUE,withGUIManagedByTheBooter)
Parameters:

agent - the agent to launch.

createFrame - if true, the kernel will launch a JFrame for this agent.

Returns:
- AbstractAgent.ReturnCode.SUCCESS : The launch has succeeded. This also means that the agent has successfully completed its activate method
- AbstractAgent.ReturnCode.ALREADY_LAUNCHED : If this agent has been already launched

launchAgent
```
public AbstractAgent.ReturnCode launchAgent(AbstractAgent agent,
                                            int timeOutSeconds,
                                            boolean createFrame)
```
Launches a new agent and returns when the agent has completed its activate() method or when timeOutSeconds seconds elapsed. That is, the launched agent has not finished its activate() before the time out time elapsed. Additionally, if createFrame is true, it tells to MaDKit that an agent GUI should be managed by the Kernel. In such a case, the kernel takes the responsibility to assign a JFrame to the agent and to manage its life cycle (e.g. if the agent ends or is killed then the JFrame is closed) Using this feature there are two possibilities:
- 1. the agent overrides the method setupFrame(AgentFrame) and so setup the default JFrame as will
- 2. the agent does not override it so that MaDKit will setup the JFrame with the default Graphical component delivered by the MaDKit platform: OutputPanel
Parameters:

agent - the agent to launch.

timeOutSeconds - time to wait for the end of the agent's activation until returning a TIMEOUT.

createFrame - if true, the kernel will launch a JFrame for this agent.

Returns:
- AbstractAgent.ReturnCode.SUCCESS : The launch has succeeded. This also means that the agent has successfully completed its activate method
- AbstractAgent.ReturnCode.ALREADY_LAUNCHED : If this agent has been already launched
- AbstractAgent.ReturnCode.TIMEOUT : If the activation time of the agent is greater than timeOutSeconds seconds
- AbstractAgent.ReturnCode.AGENT_CRASH : If the agent crashed during its activate method
Since:

MaDKit 5.0

launchAgent
```
public AbstractAgent launchAgent(String agentClass)
```
Launches a new agent using its full class name.
This has the same effect as launchAgent(agentClass, Integer.MAX_VALUE, false).

Parameters:

agentClass - the full class name of the agent to launch

Returns:

the instance of the launched agent or null if the operation times out or failed.

launchAgent
```
public AbstractAgent launchAgent(String agentClass,
                                 int timeOutSeconds)
```
Launches a new agent using its full class name.
This has the same effect as launchAgent(agentClass, timeOutSeconds, false).

Parameters:

timeOutSeconds - time to wait the end of the agent's activation until returning null

agentClass - the full class name of the agent to launch

Returns:

the instance of the launched agent or null if the operation times out or failed.

launchAgent
```
public AbstractAgent launchAgent(String agentClass,
                                 boolean createFrame)
```
Launches a new agent using its full class name.
This has the same effect as launchAgent(agentClass, Integer.MAX_VALUE, defaultGUI).

Parameters:

createFrame - if true a default GUI will be associated with the launched agent

agentClass - the full class name of the agent to launch

Returns:

the instance of the launched agent or null if the operation times out or failed.

launchAgent
```
public AbstractAgent launchAgent(String agentClass,
                                 int timeOutSeconds,
                                 boolean createFrame)
```
Launches a new agent using its full class name and returns when the launched agent has completed its activate() method or when the time out is elapsed. This has the same effect as launchAgent(AbstractAgent, int, boolean) but allows to launch agent using a class name found reflexively. The targeted agent class should have a default constructor for this to work. Additionally, this method will launch the last compiled byte code of the corresponding class if it has been reloaded using MadkitClassLoader.reloadClass(String). Finally, if the launch timely succeeded, this method returns the instance of the created agent.

Parameters:

timeOutSeconds - time to wait the end of the agent's activation until returning null

createFrame - if true a default GUI will be associated with the launched agent

agentClass - the full class name of the agent to launch

Returns:

the instance of the launched agent or null if the operation times out or failed.

launchAgentBucket
```
public List<AbstractAgent> launchAgentBucket(String agentClass,
                                             int bucketSize,
                                             int cpuCoreNb,
                                             String... roles)
```
Optimizes mass agent launching. Launches bucketSize instances of agentClassName (an agent class) and put them in the artificial society at the locations defined by cgrLocations. Each string of the cgrLocations array defines a complete CGR location. So for example, cgrLocations could be defined and used with code such as :
```
 launchAgentBucketWithRoles("madkit.bees.Bee", 1000000, "community,group,role", "anotherC,anotherG,anotherR")
 
```
In this example all the agents created by this process will have these two roles in the artificial society, even if they do not request them in their activate() method.
Additionally, in order to avoid to change the code of the agent considering how they will be launched (using the bucket mode or not). One should use the following alternative of the usual request methods : bucketModeCreateGroup(String, String, boolean, Gatekeeper), bucketModeRequestRole(String, String, String, Object): If used in activate(), these requests will be ignored when the bucket mode is used or normally proceeded otherwise.
If some of the corresponding groups do not exist before this call, the caller agent will automatically become the manager of these groups.
Parameters:

agentClass - the name of the class from which the agents should be built.

bucketSize - the desired number of instances.

cpuCoreNb - the number of parallel tasks to use. Beware that if cpuCoreNb is greater than 1, the agents' constructors and activate() methods will be called simultaneously so that one has to be careful if shared resources are accessed by the agents

roles - default locations in the artificial society for the launched agents. Each string of the cgrLocations array defines a complete CGR location by separating C, G and R with commas as follows: "community,group,role". It can be null.

Returns:

a list containing all the agents which have been launched, or null if the operation has failed

Since:

MaDKit 5.0.0.6

launchAgentBucket
```
public List<AbstractAgent> launchAgentBucket(String agentClass,

roles - default locations in the artificial society for the launched agents. Each string of the cgrLocations array defines a complete CGR location by separating C, G and R with commas as follows: "community,group,role". It can be null

launchAgentBucket
```
public void launchAgentBucket(List<? extends AbstractAgent> bucket,
                              int nbOfParallelTasks,
                              String... roles)
```
Similar to launchAgentBucket(String, int, String...) except that the list of agents to launch is given. Especially, this could be used when the agents have no default constructor.

Parameters:

bucket - the list of agents to launch

nbOfParallelTasks - the number of parallel tasks to use for launching the agents. Beware that if nbOfParallelTasks is greater than 1, the agents' activate() methods will be called simultaneously so that one has to be careful if shared resources are accessed

roles - default locations in the artificial society for the launched agents. Each string of the cgrLocations array defines a complete CGR location by separating C, G and R with commas as follows: "community,group,role". It can be null

killAgent
```
public AbstractAgent.ReturnCode killAgent(AbstractAgent target)
```
Kills the targeted agent. This has the same effect as killAgent(target,Integer.MAX_VALUE) so that the targeted agent has a lot of time to complete its end() method.
Returns:
- AbstractAgent.ReturnCode.SUCCESS: If the target's end method has completed normally.
- AbstractAgent.ReturnCode.ALREADY_KILLED: If the target has been already killed.
- AbstractAgent.ReturnCode.NOT_YET_LAUNCHED: If the target has not been launched.
- AbstractAgent.ReturnCode.TIMEOUT: If the target's end method took more than 2e31 seconds and has been brutally stopped: This unlikely happens ;).

killAgent
```
public AbstractAgent.ReturnCode killAgent(AbstractAgent target,
                                          int timeOutSeconds)
```
Kills the targeted agent. The kill process stops the agent's life cycle but allows it to process its end() method until the time out elapsed.
If the target is in the activate or live method (Agent subclasses), it will be brutally stop and then proceed its end method.
The method returns only when the targeted agent actually ends its life. So if the target contains a infinite loop, the caller can be blocked. Using a timeout thus ensures that the caller will be blocked only a certain amount of time. Using 0 as timeout will stop the target as soon as possible, eventually brutally stop its life cycle. In such a case, if its end method has not been started, it will never run.
Returns:
- AbstractAgent.ReturnCode.SUCCESS: If the target's end method has completed normally.
- AbstractAgent.ReturnCode.ALREADY_KILLED: If the target has been already killed.
- AbstractAgent.ReturnCode.NOT_YET_LAUNCHED: If the target has not been launched.
- AbstractAgent.ReturnCode.TIMEOUT: If the target's end method took too much time and has been brutally stopped.

getName
```
public String getName()
```
The agent's name.

Returns:

the name to display in logger info, GUI title and so on. Default is "class name + internal ID"

setName
```
public void setName(String name)
```
Changes the agent's name

Parameters:

name - the name to display in logger info, GUI title and so on, default is "class name + internal ID"

setLogLevel
```
@Deprecated
public void setLogLevel(Level newLevel)
```
Deprecated. as of MaDKit 5.2, AgentLogger.setLevel(Level) should now be used through getLogger()

Sets the agent's log level. This should be used instead of directly AgentLogger.setLevel(Level) because this also works when logger is null and allows to set it to null to save cpu time.

Parameters:

newLevel - The log level under which log messages are displayed. If Level.OFF is used then logger is set to null

getLogger
```
public AgentLogger getLogger()
```
Returns the agent's logger. It is lazily created so that if getLogger() is not used, there is no memory foot print at all, which could be crucial when working with thousands of abstract agents in simulation mode.

Returns:

the agent's logger.

Parameters:

other - the agent to be compared.

Returns:

a negative integer, a positive integer or zero as this agent has been instantiated before, after or is the same agent than the specified agent.

                                            Gatekeeper keyMaster)
```
Creates a new Group within a community.
If this operation succeed, the agent will automatically handle the role defined by DefaultMaDKitRoles.GROUP_MANAGER_ROLE, which value is "manager", in this created group. Especially, if the agent leaves the role of "manager", it will also automatically leave the group and thus all the roles it has in this group.
Agents that want to enter the group may send messages to the "manager" using the role defined by DefaultMaDKitRoles.GROUP_CANDIDATE_ROLE, which value is "candidate".
Parameters:

community - the community within which the group will be created. If this community does not exist it will be created.

group - the name of the new group.

isDistributed - if true the new group will be distributed when multiple MaDKit kernels are connected.

keyMaster - any object that implements the Gatekeeper interface. If not null, this object will be used to check if an agent can be admitted in the group. When this object is null, there is no group access control.

Returns:
- AbstractAgent.ReturnCode.SUCCESS: If the group has been successfully created.
- AbstractAgent.ReturnCode.ALREADY_GROUP: If the operation failed because such a group already exists.
- AbstractAgent.ReturnCode.IGNORED: If the agent has been launched using a launchAgentBucket method such as launchAgentBucket(List, String...) with non null roles. This for optimization purposes.

See Also:

XMLUtilities

getState
```
public AbstractAgent.State getState()
```
Returns the current state of the agent in the MaDKit platform. This method provides a way of knowing what is the current state of the agent regarding its life cycle. This could be convenient when you design a method that could work differently depending on the actual state of the agent.
Returns:
the current state of the agent:
- AbstractAgent.State.NOT_LAUNCHED: the agent has not been launched yet. This especially means that most of the methods of this API still do not work for this agent as it has not been registered yet.
- AbstractAgent.State.INITIALIZING: the agent is being registered by the kernel but has not started its activate() method yet.
- AbstractAgent.State.ACTIVATED: the agent is processing its activate() method. This state is also the "running" state of AbstractAgent subclasses (i.e. when they have finished their activation) as they do not have a Agent.live() managed by the kernel in their life cycle. On the contrary to Agent subclasses which next state is AbstractAgent.State.LIVING.
- AbstractAgent.State.LIVING: returned when Agent subclasses are processing their Agent.live() method.
- AbstractAgent.State.ENDING: the agent is processing its end() method.
- AbstractAgent.State.TERMINATED: the agent has finished its life in the MaDKit platform. Especially, most of the methods of this API will no longer work for this agent.
