Enum Constant Detail

NONE

public static final DelayedNeighborsPerception.Anticipation NONE

Assume no anticipation.

CONSTANT_SPEED

public static final DelayedNeighborsPerception.Anticipation CONSTANT_SPEED

Assume constant speed.

CONSTANT_ACCELERATION

public static final DelayedNeighborsPerception.Anticipation CONSTANT_ACCELERATION

Assume constant acceleration.

Method Detail

values

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

Returns:

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

valueOf

public static DelayedNeighborsPerception.Anticipation 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

Anticipate movement.

Parameters:

neighborTriplet - headway, speed and acceleration

duration - duration

traveledDistance - distance the subject vehicle traveled during the anticipation time

Returns:

anticipated info
