public void dispatchSubgoalAndListen(Goal subgoal)

Description copied from interface: PlanBody

Dispatches a subgoal to be achieved and registers itself as a listener to receive a notification of the end of execution of the goal.

Specified by:

dispatchSubgoalAndListen in interface PlanBody

Parameters:

subgoal - the subgoal to be dispatched.

getBeliefBase

public BeliefBase getBeliefBase()

Description copied from interface: PlanBody

Returns the belief base of the capability.

Specified by:

getBeliefBase in interface PlanBody

Returns:

the belief base containing the beliefs.

getEndState

public Plan.EndState getEndState()

Description copied from interface: PlanBody

Returns the end state of the execution of this plan.

Specified by:

getEndState in interface PlanBody

Returns:

the end state of this plan, or null if it has not finished yet.

getGoal

public Goal getGoal()

Description copied from interface: PlanBody

Returns the goal to be achieved by this plan instance.

Specified by:

getGoal in interface PlanBody

Returns:

the goal.

getGoalEvent

public GoalEvent getGoalEvent()

Description copied from interface: PlanBody

Returns a goal event from the queue. If the queue is empty, the behavior associated with this plan instance is blocked.

Specified by:

getGoalEvent in interface PlanBody

Returns:

the goal event or null if the queue is empty.

getGoalEvent

public GoalEvent getGoalEvent(boolean block)

Description copied from interface: PlanBody

Returns a goal event from the queue. If the queue is empty, the behavior associated with this plan instance is going to be blocked if the parameter passed to this method is true.

Specified by:

getGoalEvent in interface PlanBody

Parameters:

block - true if the behavior must be blocked if the queue is empty.

Returns:

the goal event or null if the queue is empty.

getGoalEvent

Notifies the listener that a goal that was performed.

Specified by:

goalPerformed in interface GoalListener

Parameters:

event - the goal event that occurred.

init

public void init(Plan plan,
                 Intention intention)
          throws PlanInstantiationException

Description copied from interface: PlanBody

Initializes this plan body. It associates this plan body with a plan definition (Plan) and an Intention. If this plan body has already been initialized, this method throws a PlanInstantiationException.

Specified by:

init in interface PlanBody

Parameters:

plan - the plan associated this this plan body.

intention - the intention that this plan instance have to achieve.

Starts the plan body, a Behaviour, associated with this plan.

Specified by:

start in interface PlanBody

stop

public void stop()

Description copied from interface: PlanBody

Stops the plan body, a Behaviour, associated with this plan. If the body implements the DisposablePlanBody, it invokes the method to about the plan body, so it can perform finalizations.

Specified by:

stop in interface PlanBody
