Class MatchList

java.lang.Object
  algorithm.matching.MatchList

public class MatchList
extends java.lang.Object

Data structure to hold assignments found in assignment algorithms. saving the matching partners in a list, as well as saving the total costs for this assignment. The matchings are saved in an order according to their matching costs.

Field Summary

private org.apache.log4j.Logger	logger logger instance
private java.util.Queue<Matching>	matchlist holding all matchings, order according to their matching costs
private double	totalcost the totalcost for all matchings

Constructor Summary

MatchList()
constructor.

Method Summary

void	addMatching(int partnerid1, int partnerid2, double cost) add a new matching.
boolean	contains(Matching matching) check if a matchlist contains a specified matching
boolean	equals(MatchList compare) check if a given matchlist contains the same matchings as the current instance.
java.util.Queue<Matching>	getMatchlist() return matchlist - list containing all found matches.
double	getMean() Get the average matching costs of this match list.
double	getMedian()
double	getStandardDeviation()
double	getTotalcost() get this matching's total cost
void	setTotalcost(double totalcost) set this matching's total cost.
java.lang.String	toString()
