Method Detail

addRule

public static List<PathEndNode> addRule(TerminalNode tn,
                                        Collection<InternalWorkingMemory> wms,
                                        RuleBase kBase)

This method is called after the rule nodes have been added to the network For add tuples are processed after the segments and pmems have been adjusted

Returns:

removeRule

public static List<PathEndNode> removeRule(TerminalNode tn,
                                           Collection<InternalWorkingMemory> wms,
                                           RuleBase kBase)

This method is called before the rule nodes are removed from the network. For remove tuples are processed before the segments and pmems have been adjusted Note the
