Constructor Details

HexagonalGeometry

public HexagonalGeometry(EvoLudo engine)

Create a hexagonal (honeycomb) geometry tied to the given engine.

Parameters:

engine - EvoLudo pacemaker

Method Details

parse

public boolean parse(String arg)

Description copied from class: AbstractGeometry

Parse geometry-specific CLI options.

Overrides:

parse in class AbstractGeometry

Parameters:

arg - the argument string without the geometry key

Returns:

true if parsing succeeded, false if invalid

init

public void init()

Generates a hexagonal (honeycomb) regular lattice with degree \(6\) (or optional self-links when connectivity is set to 1). Fixed boundaries truncate neighbours; periodic boundaries wrap the lattice.

Specified by:

init in class AbstractGeometry

initK1

private void initK1()

Initialize the lattice with self-links only (connectivity 1).

fillEvenIRows

private void fillEvenIRows(int side,
 boolean interspecies,
 int x,
 int u,
 boolean uNowrap,
 int d)

Populate even-index rows for the hexagonal lattice, respecting boundary conditions.

Parameters:

side - side length of the lattice

interspecies - true if interspecific interactions allow self-links

x - offset for the current row

u - index offset for the row above

uNowrap - true if wrapping upward is allowed

d - index offset for the row below

fillOddIRows

private void fillOddIRows(int side,
 boolean interspecies,
 int x,
 int u,
 int d,
 boolean dNowrap)

Populate odd-index rows for the hexagonal lattice, respecting boundary conditions.

Parameters:

side - side length of the lattice

interspecies - true if interspecific interactions allow self-links

x - offset for the current row

u - index offset for the row above

d - index offset for the row below

dNowrap - true if wrapping downward is allowed

checkSettings

protected boolean checkSettings()

Description copied from class: AbstractGeometry

Hook for subclasses to implement geometry specific checks.

Overrides:

checkSettings in class AbstractGeometry

Returns:

true if adjustments require a reset
