> IterativeCondition only exposes the filter interface. For the aggregation 
> operation in the condition, since the condition may be called multiple times 
> in the NFA process, an event may cause the custom aggregation state in the 
> condition to be updated multiple times, for example, filters goods with a 
> total of more than 1000 orders in the past 10 minutes. AggregateFunction is 
> introduced in IterativeCondition to initialize and maintain aggregation state.
