All Implemented Interfaces:

java.lang.Cloneable

public class Euclidean
extends RuleFamily

Implements euclidean cellular automaton which has an infinite neighbourhood with weights that drop off with f(r) where r is the euclidean / manhattan distance TODO (Fix freaking floating-point summation)

public Euclidean(java.lang.String rulestring)

Method Details

fromRulestring

protected void fromRulestring(java.lang.String rulestring)

Description copied from class: RuleFamily

Loads the rule's parameters from a rulestring

Specified by:

fromRulestring in class RuleFamily

Parameters:

rulestring - The rulestring of the rule (eg. B3/S23, R2,C2,S5-9,B7-8,NM)

canonise

public java.lang.String canonise(java.lang.String rulestring)

Description copied from class: RuleFamily

Canonises the inputted rulestring with the currently loaded parameters. This method should be called whenever the parameters of a rule are updated.

Specified by:

canonise in class RuleFamily

Parameters:

rulestring - The rulestring to canonised

Returns:

Canonised rulestring

getRegex

public java.lang.String[] getRegex()

Description copied from class: RuleFamily

The regexes that will match a valid rulestring

Specified by:

getRegex in class RuleFamily

Returns:

An array of regexes that will match a valid rulestring

getDescription

public java.lang.String getDescription()

Description copied from class: RuleFamily

Returns a plain text description of the rule family to be displayed in the Rule Dialog

Specified by:

getDescription in class RuleFamily

Returns:

Description of the rule family

clone

public java.lang.Object clone()

Description copied from class: RuleFamily

Clones the object

Specified by:

clone in class RuleFamily

Returns:

A deepcopy of the object

getNeighbourhood

public Coordinate[] getNeighbourhood(int generation)

Description copied from class: Rule

This method returns the neighbourhood of a given cell at a certain generation

Specified by:

getNeighbourhood in class Rule

Parameters:

generation - The generation of the simulation

Returns:

A list of Coordinates that represent the neighbourhood

transitionFunc

public int transitionFunc(int[] neighbours, int cellState, int generations, Coordinate coordinate)

Description copied from class: Rule

This method represents the transition function of the rule

Specified by:

transitionFunc in class Rule

Parameters:

neighbours - The cell's neighbours in the order of the neighbourhood provided

cellState - The current state of the cell

generations - The current generation of the simulation

coordinate - The coordinate of the cell

Returns:

The state of the cell in the next generation

step

public void step(Grid grid, java.util.ArrayList<java.util.Set<Coordinate>> cellsChanged, int generation, java.util.function.Function<Coordinate,java.lang.Boolean> step) throws java.lang.IllegalArgumentException

Description copied from class: Rule

Steps the grid provided forward one generation

Overrides:

step in class Rule

Parameters:

grid - The grid that will be stepped forward one generation

cellsChanged - An array of sets that contains the cells the changed in the previous generations. The first entry will contains the cells that changed in the previous generation and the next entry will contain the cells that changed the previous previous generation and so on. It should be the same length as the alternating period of the rule

generation - The current generation of the simulation

step - A function that returns whether the cell at that coordinate should be stepped forward.

Throws:

java.lang.IllegalArgumentException - Thrown if the length of cellsChanged is not the same as the alternating period
