  +--life.Life

Direct Known Subclasses:

GBLife

public abstract class Life

extends java.lang.Object

Heavily optimised implementation of Conway's Life genetic algorithim. This version includes loop invariant, loop reversal, and local caching optimisations that are normally the responsibility of the compiler.

Field Summary

protected byte[][]	age Age of this cell.
protected byte[][]	count Number of alive neighbours
protected int	dx Dimensions of the field, minus 1
protected int	dy Dimensions of the field, minus 1

Constructor Summary

Life(int dx, int dy)
Create a new Life board with the given width and height

Method Summary

protected void	countNeighbours() Scan the current board and compute the neighbour count.
protected void	evolve() Evolve the cells on the board based on the neighbour count.
protected abstract void	render() Implemented by the sub class to render the board
protected void	update() Scans the board, updating the neighbours count and computes the next board.
