Class ajanta.agent.TargetedState 

java.lang.Object

   +----ajanta.agent.TargetedState
public class TargetedState
extends Object
In some applications, an agent programmer needs to protect items in the agent's state such that they are only accessible to certain servers . Items are targeted towards particular servers, and need to be selectively revealed to those servers alone. To facilitate this, we provide a TargetedState object in Ajanta's generic agent.
