Class FeasibleSpaceExplorer

java.lang.Object
  org.decisiondeck.xmcda_oo.utils.FeasibleSpaceExplorer

All Implemented Interfaces:

Iterator<AlternativeEvaluations>, AlternativeSpaceExplorer

public class FeasibleSpaceExplorer
extends Object
implements AlternativeSpaceExplorer

This object allows to explore a space of alternatives. It will iterate through all alternatives that are not better than those the user has marked as maximal. This object will return every alternative possible in the given space, except those that would dominate one marked as maximal.

Constructor Summary

Method Summary

boolean	hasNext()
AlternativeEvaluations	next()
boolean	overMaximal(Map<Criterion,Double> alternative) The given alternative must be evaluated on the criteria bound to this object.
void	remove() Throws UnsupportedOperationException.
