Class Maze

java.lang.Object

mazealgo.model.algorithms.mazeGenerators.Maze

All Implemented Interfaces:

Serializable

public class Maze
extends Object
implements Serializable

A 2D maze: an int grid where 1 is a wall and 0 is a passable cell, with a start position and a goal position.

Two wire formats:

• Default Java serialization (via Serializable) — convenient but verbose. Used by SolveMazeStrategy where the maze travels client-to-server once and the overhead doesn't dominate.
• toByteArray() / Maze(byte[]) — compact, fixed header + flat grid bytes. Wrapped by MyCompressorOutputStream's run-length encoding when shipping back from GenerateMazeStrategy.

Constructor Details

Maze

public Maze(int rows,
 int columns)

Maze

public Maze(byte[] bytes)

Reconstructs a maze from toByteArray(). Throws IllegalArgumentException if the byte stream is truncated or malformed (typically: caller passed something that wasn't produced by toByteArray).

Method Details

toByteArray

public byte[] toByteArray()

Compact byte representation: six big-endian ints (rows, columns, start row/col, goal row/col) followed by rows*columns single bytes — one per cell, value 0 or 1. Mirrored by Maze(byte[]).

The grid portion is what MyCompressorOutputStream runs RLE over; the header is varied enough that compression doesn't help it, but the grid (long runs of 0 or 1) shrinks dramatically.

getRows

public int getRows()

getColumns

public int getColumns()

getCell

public int getCell(int row,
 int column)

setCell

public void setCell(int row,
 int column,
 int value)

getStartPosition

public Position getStartPosition()

setStartPosition

public void setStartPosition(Position start)

getGoalPosition

public Position getGoalPosition()

setGoalPosition

public void setGoalPosition(Position goal)

print

public void print()

Prints the maze. Walls are 1, passages are 0, the start is marked S and the goal is marked E.
