      • getPruningEvent

        public int getPruningEvent​(Var variable)
        Description copied from interface: VarHandler
        Retrieves the consistency pruning event of a handler variable that causes the handler to be reevaluated. For instance, X- and W-variables will listen to BOUND events while S-variables typically consider ANY events.
        Specified by:
        getPruningEvent in interface VarHandler
        Parameters:
        variable - a handler variable
        Returns:
        the pruning event which causes reevaluation of the handler

      • listVariables

        public java.util.List<IntVar> listVariables()
        Specified by:
        listVariables in interface VarHandler
        Returns:
        the list of variables handled by this handler

      • processEvent

        public void processEvent​(IntVar variable,
                         MutableNetwork network)
        Description copied from interface: VarHandler
        Informs the handler that one of its variable has changed and asks the handler to update the state of the network accordingly.
        Specified by:
        processEvent in interface VarHandler
        Parameters:
        variable - the variable that changed
        network - the network
