public abstract class AbstractObservableAgent

extends java.util.Observable

implements Agent

Optional basis for class implementing Agent interface. Derived classes constructor must fill the protected variables. Add necessary Agent information and properties. In general setEvalMode should be overrided. Same as AbstractAgent, but derived from java.util.Observer.

Agent could themselves notify their oberver by the end ot the Agent.requestAction(lnsc.page.State) process, or should at least call #setChanged(). notifyObservers() send a {@link #toDataSet} description by default.

Agents are assumed serializable! Episode state information should be transient! The observers list is not!

Method Summary

boolean	getEvalMode() Indicates whether the agent is in evaluation mode.
boolean	isAdaptive() Indicates whether the agent is static (never adapts, no learning) or adaptives (the agents learn).
boolean	isEvaluable() Indicates whether the agent can be placed in eval mode.
void	notifyObservers()
void	setEvalMode(boolean newEvalMode) Sets the agent in evaluation mode, that is, no training should append.
DataSet	toDataSet() Similar to the toString method, but return state content in the form of a DataSet.

Method Detail

getEvalMode

public boolean getEvalMode()

Description copied from interface: Agent

Indicates whether the agent is in evaluation mode.

Specified by:

getEvalMode in interface Agent

Returns:

true if it is in evaluation mode. false if it is in normal possibly adaptive mode.

isAdaptive

public boolean isAdaptive()

Description copied from interface: Agent

Indicates whether the agent is static (never adapts, no learning) or adaptives (the agents learn).

Specified by:

isAdaptive in interface Agent

Returns:

true if the agent can learns or adapt when eval mode is true, false if the agent never adapts (i.e. always in eval mode).

isEvaluable

public boolean isEvaluable()

Description copied from interface: Agent

Indicates whether the agent can be placed in eval mode.

Specified by:

isEvaluable in interface Agent

Returns:

true if the agent can be placed in eval mode. false if the agent is always adapting anyway.

notifyObservers

public void notifyObservers()

Overrides:

notifyObservers in class java.util.Observable

setEvalMode

public void setEvalMode(boolean newEvalMode)

Description copied from interface: Agent

Sets the agent in evaluation mode, that is, no training should append.

Specified by:

setEvalMode in interface Agent

Parameters:

newEvalMode - true to set it into evaluation mode. false to set it into normal possibly adaptive mode.

toDataSet

public DataSet toDataSet()

Description copied from interface: Agent

Similar to the toString method, but return state content in the form of a DataSet. Can be null.

Specified by:

toDataSet in interface Agent

Returns:

A DataSet containing a description of the State.
