public class desire
extends intend

Internal action: .desire(D, [ I ]).

Description: checks whether D is a desire: D is a desire either if there is an event with +!D as triggering event or it is a goal in one of the agent's intentions I.

Example:

• .desire(go(1,3)): true if go(1,3) is a desire of the agent.
• .desire(go(1,3), I): as above and I unifies with the intention that contains the desire. I is the identification of the intention. The internal action .intention can be used to further inspect the state of the intention.
