public abstract class Generator
extends java.lang.Object

This is the interface for an N digit number game guess generator. Derive a class from this one with a constructor and the methods given here to implement some algorithm for generating guesses.

A Guesser repeatedly calls nextGuess() to get the next guess and then tellScore() to give the Generator the score for the last guess.

Constructor Summary

Generator()

Method Summary

abstract boolean	nextGuess(Numbah guess) makes the next guess
abstract void	retractScore() backs up the generator to the state before the last nextGuess()
abstract void	tellScore(Score score) is told a score for the last guess

public Generator()

Method Detail

nextGuess

public abstract boolean nextGuess(Numbah guess)

makes the next guess

Parameters:

guess - the guess that gets generated, if possible

Returns:

true iff it was possible to generate a next guess, if not, the "guess" does not change, and the previous score is forgotten

tellScore

public abstract void tellScore(Score score)

is told a score for the last guess

Parameters:

score - the score for the last guess - the score must be legit, though may be inconsistent with previous scores in which case nextGuess() will return false

retractScore

public abstract void retractScore()

backs up the generator to the state before the last nextGuess()
