4. DisplayRegistry Keeps track of all registered displays –register(d:Display) Registers a new display –unregister(d:Display) Unregister a display. If the passed display has not been registered yet this method should have any effect.

5. AgentRegistry Keeps track of all registered agents –register(a:Agent) Registers a new agent –unregister(a:Agent) Unregister an agent. If the passed agent has not been registered yet this method should have any effect.

6. SimulationAdmin run() –Start simulation stop() –Stops current simulation –If the simulation is already stopped this method should have no effect. getState() : SimulationState –Returns current simulation state getEnvironmentAgent() : Agent –Returns the agent driving simulation

7. SimulationAdmin State Machine CREATED RUNNING STOPPED run() stop()

9. ClientFacade init(serverURL:String) –Connects to server exportObject(obj:Remote) : Remote –Returns a remote stub from a local object –Every object that is supposed to be accessed remotely should be exported first. exportAgent(realAgent:Object, agentInterface:Class) –Creates a proxy for the agent and exports it getProxiedEnvironment(environmentInterface : Class) –Creates a proxy for the environment and returns it

10. ServerFacade init(port:Integer, environmentAgent : EnvironmentAgent) –Starts server initProxiedEnvironment (port:Integer, envAgent :EnvironmentCycleProcessor) –Starts server getProxyForRemoteAgent(proxyInterface: Class, remoteAgent:Agent) : Object
