Class Perception

java.lang.Object

br.unicamp.cst.core.entities.Codelet

br.unicamp.cst.perception.Perception

All Implemented Interfaces:

MemoryObserver, java.lang.Runnable

public abstract class Perception
extends Codelet

This Perception class allows us to create codelets with additional methods. A perception codelet has the property of always sending its output memory objects to working storage. Note: A Perception Codelet clears its output list at every iteration.

Method Summary

Modifier and Type	Method and Description
void	addOutput(Memory output) This method adds an output memory in the output list.
void	pushDetectedPercept(Memory pe) This method pushes a memory object representing a percept detected in the world into a list, so this perception codelet knows what is true.
void	removesOutput(Memory output) This method removes an output memory in the output list.
void	uptadeOutputWithPercepts() This method makes sure all detected percepts are kept in this codelet's output list.

Method Detail

pushDetectedPercept

public void pushDetectedPercept(Memory pe)

This method pushes a memory object representing a percept detected in the world into a list, so this perception codelet knows what is true. Important: Remember to call uptadeOutputWithPercepts() in order to keep pushed percepts into this codelet's output list.

Parameters:

pe -

uptadeOutputWithPercepts

public void uptadeOutputWithPercepts()

This method makes sure all detected percepts are kept in this codelet's output list. All known percepts that were not detected should be removed from output list if any of them are still there. Being a Perception codelet, it keeps its output list synched with Working Storage at all times.

addOutput

public void addOutput(Memory output)

This method adds an output memory in the output list.

Overrides:

addOutput in class Codelet

Parameters:

output -

removesOutput

public void removesOutput(Memory output)

This method removes an output memory in the output list.

Overrides:

removesOutput in class Codelet

Parameters:

output -
