org.opentrafficsim.core.gtu.GTUDirectionality

All Implemented Interfaces:

Serializable, Comparable<GTUDirectionality>

public enum GTUDirectionality
extends Enum<GTUDirectionality>

Longitudinal driving directions for a GTU. The driving directions can be used on a link or a lane. The two possible values are DIR_PLUS and DIR_MINUS.

Enum Constant Detail

DIR_PLUS

public static final GTUDirectionality DIR_PLUS

Driving direction matches the direction of the graph, increasing fractional position when driving in this direction.

DIR_MINUS

public static final GTUDirectionality DIR_MINUS

Driving direction opposite to the direction of the graph, decreasing fractional position when driving in this direction.

Method Detail

values

public static GTUDirectionality[] 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 (GTUDirectionality c : GTUDirectionality.values())
    System.out.println(c);

Returns:

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

valueOf

public static GTUDirectionality 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

isPlus

public boolean isPlus()

Returns:

whether the gtu drives in the design direction on the link

isMinus

public boolean isMinus()

Returns:

whether the gtu drives against the design direction on the link

flip

public GTUDirectionality flip()

Returns the flipped direction.

Returns:

GTUDirectionality; flipped direction.
