Constructor Detail

GradualApproval

public GradualApproval(int numCandidates)

In addition to interfaced methods, there shall be a constructor taking the integer number N of choices to be voted on.

Method Detail

init

public VotingSystem init(java.lang.String[] argv)

Arguments to modify behavior of GradualApproval

Overrides:

init in class VotingSystem

Returns:

this so that you can do

vs = (new VS(numc)).init( new String[]{"blah", "grunt"} );

voteRating

public int voteRating(int[] rating)

Overrides:

voteRating in class RatedVotingSystem

Parameters:

rating - An array int[numc]. rating[i] is the rating of choice i. A rating can be any int value. Higher means more preferred. NO_VOTE for unrated.

Returns:

0 on success

voteRating

public int voteRating(float[] rating)

Specified by:

voteRating in class VotingSystem

Parameters:

rating - An array int[N]. rating[i] is the rating of choice i. A rating can be any int value. Higher means more preferred. NO_VOTE for unrated.

Returns:

0 on success

voteRating

public int voteRating(double[] rating)

Overrides:

voteRating in class RatedVotingSystem

Parameters:

rating - An array int[N]. rating[i] is the rating of choice i. A rating can be any int value. Higher means more preferred. NO_VOTE for unrated.

Returns:

0 on success

getWinners

public int[] getWinners()

Do processing if necessary, return winners. It might be a good idea to implement getWinners(java.io.PrintWriter) and implement this to call it with null.

Specified by:

getWinners in class VotingSystem

Returns:

indecies of winners (hopefully 1 of them)

getWinners

public int[] getWinners(int numSeats)

Do processing if necessary, return winners. Default implementation returns null so that not all systems have to be multi-seat systems.

It is recommended to cache the return value in such a way that calling this function again does not do complex recalculation. That cache should be cleared if voteRating or voteRanking is called.

Overrides:

getWinners in class VotingSystem

Parameters:

numSeats - the number of seats available.

Returns:

indecies of winners, hopefully numSeats of them but in case of ties there may be more and in case of some internal schism there may be fewer. Check .length to be sure.

toString

public java.lang.String toString(java.lang.String[] names)

A more interesting representation. Include the names of the choices voted upon in the representation.

Specified by:

toString in class VotingSystem

Parameters:

names - The names of the choices.

Returns:

state, with names!

htmlSummary

public java.lang.String htmlSummary(java.lang.String[] names)

A fancy html representation. Include the names of the choices voted upon in the representation.

Specified by:

htmlSummary in class VotingSystem

Parameters:

names - The names of the choices. May be null.

Returns:

state, with names!

name

public java.lang.String name()

Description copied from class: VotingSystem

Return name of this voting system. This is a function so that it can potentially construct a detailed name based on options set in init().

Overrides:

name in class VotingSystem

Returns:

a descriptive name
