public class suspended
extends DefaultInternalAction

Internal action: .suspended(G, R).

Description: checks whether goal G belongs to a suspended intention. R (a term) unifies with the reason for the suspend (waiting action to be performed, .wait, ....). The literal G represents a suspended goal if there is a triggering event +!G in any plan within any intention in PI or PA.

Example:

• .suspended(go(1,3),R): true if go(1,3) is a suspended goal. R unifies with "act" if the reason for being suspended is an action waiting feedback from environment.
