Class SceneChangeListener

java.lang.Object

org.jactr.modules.pm.visual.scene.SceneChangeListener

All Implemented Interfaces:

ICommonRealityListener, IAfferentListener, IObjectListener<IAfferentObject>, IFeatureMapListener

public class SceneChangeListener
extends java.lang.Object
implements IFeatureMapListener, IAfferentListener

Scene change listener that implements both IVisualFeatureMapListener to track changes to the IVisualModule's IVisualMap's feature maps, and IAfferentListener which allows the listener to circumvent the visual module and go straight to the source of the percepts.

The listener works by collecting the IIdentifiers of all the percepts that change between calls to reset(), call to check() will recompute the change ratio ( getChangeRatio() ).
