Class succeed_goal

java.lang.Object
  jason.asSemantics.DefaultInternalAction
      jason.stdlib.succeed_goal

All Implemented Interfaces:

InternalAction, java.io.Serializable

Direct Known Subclasses:

fail_goal

public class succeed_goal
extends DefaultInternalAction

Internal action: .succeed_goal(G).

Description: remove goals G from the agent circumstance as if a plan for such goal had successfully finished. G is a goal if there is a triggering event +!G in any plan within any intention; also note that intentions can be suspended hence appearing in E, PA, or PI as well.

Example:

• .succeed_goal(go(X,3)): stops any attempt to achieve goals such as !go(1,3) as if it had already been achieved.

(Note: this internal action was introduced in a DALT 2006 paper, where it was called .dropGoal(G,true).)
