Method Detail

action

public void action()

This method tries to achieve all subgoals of the SequentialGoal to be achieved sequentially. If one of the subgoals fail, it stops the plan body execution.

Specified by:

action in class jade.core.behaviours.Behaviour

See Also:

Behaviour.action()

onStart

public void onStart()

Initializes this plan. Starts the goals iterator and verifies if the goal that triggered this plan body execution is a SequentialGoal. If not, it throws an IllegalArgumentException.

Specified by:

onStart in interface PlanBody

Overrides:

onStart in class jade.core.behaviours.Behaviour

See Also:

Behaviour.onStart()

setGoalOutput

public void setGoalOutput(Goal goal)

Sets completed goals, and the failed goal, if there is one.

Specified by:

setGoalOutput in interface OutputPlanBody

Parameters:

goal - the goal whose output parameters are to be set.

See Also:

OutputPlanBody.setGoalOutput(bdi4jade.goal.Goal)

setNextGoal

protected void setNextGoal(Goal previousGoal,
                           Goal goal)
                    throws ParameterException
