java.lang.Object jason.environment.Environment jason.environment.TimeSteppedEnvironment
public class TimeSteppedEnvironment
General environment class that "synchronise" all agents actions. It waits one action for each agent and, when all actions is received, executes them.
Nested Class Summary | |
---|---|
static class |
TimeSteppedEnvironment.OverActionsPolicy
Policy used when a second action is requested and the agent still has another action pending execution |

Method Summary | |

Structure |
getActionInSchedule(java.lang.String agName)
|
int |
getNbAgs()
Returns the number of agents in the MAS (used to test the end of a cycle) |
java.util.List<Literal> |
getPercepts(java.lang.String agName)
stops perception while executing the step's actions |
int |
getStep()
returns the current step counter |
void |
init(java.lang.String[] args)
Called before the MAS execution with the args informed in .mas2j project, the user environment could override it. |
protected int |
requiredStepsForAction(java.lang.String agName,
Structure action)
|
void |
scheduleAction(java.lang.String agName,
Structure action,
java.lang.Object infraData)
Called by the agent infrastructure to schedule an action to be executed on the environment |
void |
setNbAgs(int n)
Set the number of agents |
void |
setOverActionsPolicy(TimeSteppedEnvironment.OverActionsPolicy p)
Sets the policy used for the second ask for an action while another action is not finished yet. |
void |
setSleep(int s)
|
protected void |
stepFinished(int step,
long elapsedTime,
boolean byTimeout)
to be overridden by the user class |
protected void |
stepStarted(int step)
to be overridden by the user class |
void |
stop()
Called just before the end of MAS execution, the user environment could override it. |
protected boolean |
testEndCycle(java.util.Set<java.lang.String> finishedAgs)
Returns true when a new cycle can start, it normally holds when all agents are in the finishedAgs set. |
protected void |
updateAgsPercept()
This method is called after the execution of the action and before to send 'continue' to the agents |
protected void |
updateNumberOfAgents()
Updates the number of agents using the environment, this default implementation, considers all agents in the MAS as actors in the environment. |
