br.unicamp.cst.core.entities.MemoryObject

All Implemented Interfaces:

Memory, java.io.Serializable

public class MemoryObject
extends java.lang.Object
implements Memory, java.io.Serializable

A Memory Object is a generic information holder, acting as a sign or an internal representation, which is responsible to store any auxiliary or perennial information necessary for the cognitive architecture to perform its behavior. Codelets and Memory Objects are intrinsically coupled to each other, in the sense that Memory Objects hold the information necessary for the Codelets to run, and are also the placeholders of any new information generated by the codelet. The main property being hold by a Memory Object is its Information (I). This information can be simply a number, or hold complex structures like lists, trees, graphs or whole networks. In our computational implementation, the information I is a generic Java Object, which can be used to represent virtually anything. A Memory Object also has two extra kinds of meta-information: a time stamp (T), which tags the Memory Object with a marker indicating its last update, and an evaluation (E), which has many different uses within CST. This evaluation is simply a number, which can be used, e.g. as an appraisal factor in an emotional module, or simply as a discriminator to differentiate among two or more Memory Objects of the same type. These meta-information can be simply ignored by simpler codelets, or be useful while implementing more sophisticated cognitive models.
