Internal action: .intend(G, [ I ] )
.
Description: checks if goal G is intended: G is intended
if there is a triggering event +!G
in any plan within an
intention I; just note that intentions can appear in E (list of events), PA (intentions with pending actions),
and PI (intentions waiting for something) as well.
This internal action backtracks all values for G.
Example:
-
.intend(go(1,3))
: is true if a plan with triggering event+!go(1,3)
appears in an intention of the agent. -
.intend(go(1,3),I)
: as above andI
unifies with the intention that contains the goal.I
is the identification of the intention. The internal action .intention can be used to further inspect the state of the intention.

execute
public java.lang.Object execute(TransitionSystem ts, Unifier un, Term[] args) throws java.lang.ExceptionDescription copied from interface:InternalAction
Executes the internal action. It should return a Boolean or an Iterator. A true boolean return means that the IA was successfully executed. An Iterator result means that there is more than one answer for this IA (e.g. see member internal action). - Specified by:
