Class MemoryContainer

java.lang.Object

br.unicamp.cst.core.entities.MemoryContainer

All Implemented Interfaces:

Memory

public class MemoryContainer
extends java.lang.Object
implements Memory

This class represents a Memory Container. The Memory Container is responsible for implementing an important element in the Dynamic Subsumption mechanism used in CST. All the Memory Objects in a Container are of the same type, and hold the same parameters. The only differences among them are that they were generated by a different codelet, and they might have different evaluations. An evaluation is an inner parameter from any Memory Object, which holds a value (usually a real value between 0 and 1) that measures a relative importance given by the codelet, and which is used by the Evaluation codelet within the Container to decide which from all input Memory Objects will be sent to the output.
