All Implemented Interfaces:

BroadcastTrigger

Direct Known Subclasses:

IndividualCoaltionActivationTrigger

public class AggregateCoalitionActivationTrigger
extends java.lang.Object
implements BroadcastTrigger

Implements a trigger that is activated when the sum of all Coalition objects in GlobalWorkspace is greater than a threshold.

Field Summary

protected GlobalWorkspace	gw Reference to the GlobalWorkspace
protected double	threshold The activation threshold

Constructor Summary

AggregateCoalitionActivationTrigger()

Method Summary

void	checkForTriggerCondition(java.util.Collection<Coalition> coalitions) Calculates the aggregate activation of all coalitions in the GlobalWorkspace and if it is over threshold a broadcast is triggered.
double	getThreshold() Gets threshold
void	init(java.util.Map<java.lang.String,java.lang.Object> parameters, GlobalWorkspace gw) This method expects a parameter with name "threshold" of type double representing the coalition activation threshold at which the trigger will fire.
void	reset() Resets the trigger.
void	start() Starts the trigger.

Method Detail

checkForTriggerCondition

public void checkForTriggerCondition(java.util.Collection<Coalition> coalitions)

Calculates the aggregate activation of all coalitions in the GlobalWorkspace and if it is over threshold a broadcast is triggered. This method is called each time a new Coalition enters the GlobalWorkspace

Specified by:

checkForTriggerCondition in interface BroadcastTrigger

Parameters:

coalitions - a Collection of all the Coalition objects in the GlobalWorkspace.

See Also:

GlobalWorkspaceImpl.addCoalition(Coalition)

reset

public void reset()

Description copied from interface: BroadcastTrigger

Resets the trigger. Called each time a new broadcast is triggered.

Specified by:

reset in interface BroadcastTrigger

init

public void init(java.util.Map<java.lang.String,java.lang.Object> parameters,
                 GlobalWorkspace gw)

This method expects a parameter with name "threshold" of type double representing the coalition activation threshold at which the trigger will fire.

Specified by:

init in interface BroadcastTrigger

Parameters:

parameters - a map for generic parameters

gw - A TriggerListener and likely a class that implements the GlobalWorkspace interface.

See Also:

BroadcastTrigger.init(Map, GlobalWorkspace)

start

public void start()

Description copied from interface: BroadcastTrigger

Starts the trigger.

Specified by:

start in interface BroadcastTrigger

getThreshold

public double getThreshold()

Gets threshold

Returns:

threshold to activate the trigger
