Scala 如何限制对本地参与者的访问
我正在为类成员搜索像Scala 如何限制对本地参与者的访问,scala,akka,actor,Scala,Akka,Actor,我正在为类成员搜索像private这样的封装方法。我想让一个参与者提供一些常见的无害消息和特权，它们可能以不希望的方式改变状态。我还可以构建代理角色，它将根据访问策略过滤消息。但是这两个参与者仍然可以通过完整路径actor ref访问。如何使某些actor ref私有化，只有其父级才能访问这些actor ref？只要使用ActorSelection知道路径，任何其他参与者都可以访问任何actor 如果您想限制某些消息，可以使用诸如package private之类的方法 假设您有Dangerou
