Class TwoInputModel.VisitedHt

java.lang.Object
  wGmdh.jGmdh.oldskul.TwoInputModel.VisitedHt

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

TwoInputModel

public class TwoInputModel.VisitedHt
extends java.lang.Object
implements java.io.Serializable

Uses a Hashtable to store pairs of Nodes and inputs for which they have calculated the output, to avoid multiple calculations of the same thing. Hashtable enables calculation if the outputs in paralell, on different Nodes, and for different inputs. (In contrast, take a single boolean flag per Node. This would allow us to mark visited subnodes in a single traversal, for a single input point, making computation in paralell impossible.)

Method Summary

boolean	isReset()
boolean	isVisited()
void	onVisit() Store the pair obtained in feed() to our Hashtable
