Enum Constant Summary

ON_SOLUTION_PATH
The state when a cell is on the solution path (the path from the start to the donut).

UNVISITED
The state when a cell has never been visited

VISIT_IN_PROGRESS
The state when a cell has been visited, but hasn't been fully processed (e.g., if its neighbors haven't been visited yet in BFS or DFS).

VISITED
The state when a cell has been traversed fully.

Method Summary

static MazeCell.CellState	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

UNVISITED

public static final MazeCell.CellState UNVISITED

The state when a cell has never been visited

VISITED

public static final MazeCell.CellState VISITED

The state when a cell has been traversed fully.

VISIT_IN_PROGRESS

public static final MazeCell.CellState VISIT_IN_PROGRESS

The state when a cell has been visited, but hasn't been fully processed (e.g., if its neighbors haven't been visited yet in BFS or DFS).

ON_SOLUTION_PATH

public static final MazeCell.CellState ON_SOLUTION_PATH

The state when a cell is on the solution path (the path from the start to the donut).

Method Detail

values

public static final MazeCell.CellState[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(MazeCell.CellState c : MazeCell.CellState.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static MazeCell.CellState valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
