Method Detail

addRule

public static void 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

removeRule

public static void 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
