Class AgentScope

java.lang.Object

cz.cuni.amis.pogamut.base.utils.guice.AgentScope

All Implemented Interfaces:

com.google.inject.Scope, IAgentScope

public class AgentScope
extends Object
implements IAgentScope

Scope used during the construction of the agent - treating all new instances (of classes annotated with AgentScoped) as singletons.

After instantiation of the agent, Pogamut calls clearScope() to release all references to instantiated objects that allows to reuse the injector again to get another instance of the agent.

We need this, because we're usually have one connection object that must be injected into two different classes thus must be treated "as a singleton for one instantiation of the agent". (This is not the only example...)

Every pogamut.base class is AgentScoped.
