org.chabala.brick.controllab.Direction

All Implemented Interfaces:

Serializable, Comparable<Direction>

public enum Direction
extends Enum<Direction>

Identifiers for the direction of output ports on the control lab.

When an output is turned on without specifying a direction, the default direction is RIGHT.

Method Detail

values

public static Direction[] values()

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

for (Direction c : Direction.values())
    System.out.println(c);

Returns:

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

valueOf

public static Direction valueOf(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:

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

NullPointerException - if the argument is null

getCode

public byte getCode()

The byte expected by the control lab for the change direction command.

Returns:

a byte relating to this direction
