public class MovingAverageAgentImpl

extends edu.mit.media.hive.agent.EventReceivingAgentImpl

implements EventFloatTranslatingAgent

Chaining agent - takes in event input from an agent, produces a time average. This has two parameters - how many milliseconds to remember, and how many milliseconds to average over. If historyLength is 300000 and averageWindow is 10000, then what we get is a 5 minute moving average of the number of events per 10 seconds.

Constructor Detail

MovingAverageAgentImpl

public MovingAverageAgentImpl()
                       throws java.rmi.RemoteException

Method Detail

doLocalSetup

public void doLocalSetup()

Description copied from class: edu.mit.media.hive.agent.AgentImpl

Handle the setup when an agent arrives on a host -- it is appropriate to allocate system resources (file descriptors, etc) here and even to locate other agents that this agent needs to communicate with. This method replaces arriveAt

---

setAverageWindow

public void setAverageWindow(int aw)

---

setHistoryLength

public void setHistoryLength(int hl)

---

buildEventCounts

protected void buildEventCounts()

---

doBehavior

public void doBehavior()

Description copied from class: edu.mit.media.hive.agent.AgentImpl

Do the basic behavior for an agent, the agent's main loop. Override this to provide your particular agent's behavior. Note: the doBehavior loop should not exit. Please call waitUntilDeath() at the end of this method, this will prevent the Cell from believing this agent prematurely exited.

---

updateAverage

protected void updateAverage()

---

getFloat

public float getFloat(edu.mit.media.hive.agent.Agent sender)

Specified by:

getFloat in interface edu.mit.media.hive.agent.FloatSourceAgent

---

notify

public void notify(edu.mit.media.hive.event.HiveEvent event)

Description copied from interface: edu.mit.media.hive.agent.EventReceivingAgent

Called when an event is sent from a source.

Specified by:

notify in interface edu.mit.media.hive.agent.EventReceivingAgent

---

getAverageWindow

public int getAverageWindow()

---

getHistoryLength

public int getHistoryLength()
