从公用事业收集的特定特征的计数代理如何？

Question

我的模型中有两种类型的代理：

1. Agenta-这是一个包裹，必须将其交付给the Deliverypoint。该代理具有相应的参数“ deliverypoint”。
2. AgentB-这是一个包含包裹（Agenta）的软件包（代理容器）。该代理商也具有一个参数“ deliverypoint”，该参数取决于目前交付的包裹（Agenta）的“递送单元”。 我需要计算符合给定条件的代理容器代理商中的代理商代理： Agenta.deliveryPoint == AgentB.DeliveryPoint

I尝试了此表达式：

count（AgentB.Contents（），p - ＆gt;（（Agenta）AgentB.Contents（））。 >

代码示例：

  private void _movingToDeliveryPoint_onExit_xjal( final com.anylogic.libraries.processmodeling.Delay<AgentB> self, AgentB agent ) {
    
traceln(count(agent.contents(), p -> ((AgentA)agent.contents()).DeliveryPoint == agent.DeliveryPoint));
  }

但是，当我运行模型时，我在执行此代码的块“ delay”（“ homingtodeLiveryPoint”）中收到此错误：

java.base/java.base/java.util.collections $ unmodifiablelist无法将其投入到SMM_CHAIN .agenta

您能帮我吗？ 多谢！

Answer 1

您不能使用AgentB.Contents（）。尽管它看起来像是一种不错的方法，但不应该被建模器使用。

另外，请勿使用==比较对象。改用equals（）方法。

这样做，假设您有agenta of agentb 的人口或列表myagentsa of：

 count(myAgentsA, a->a.DeliveryPoint.equals(DeliveryPoint))

这是假设您从agentb中调用代码
