All Implemented Interfaces:

Serializable, Comparable<RollingLaneStructureRecord.RecordLink>

Enclosing class:

RollingLaneStructureRecord

public static enum RollingLaneStructureRecord.RecordLink
extends Enum<RollingLaneStructureRecord.RecordLink>

Link between records that defines the dependence of start position and hence how this is updated as the GTU moves.

Enum Constant Summary

Enum Constants

Enum Constant	Description
CROSS	Part of the current cross-section.
DOWN	This record is downstream of the start distance source.
LATERAL_END	This record is laterally adjacent to the start distance source, and found in an upstream search.

Enum Constant Detail

UP

public static final RollingLaneStructureRecord.RecordLink UP

This record is upstream of the start distance source.

DOWN

public static final RollingLaneStructureRecord.RecordLink DOWN

This record is downstream of the start distance source.

LATERAL_END

public static final RollingLaneStructureRecord.RecordLink LATERAL_END

This record is laterally adjacent to the start distance source, and found in an upstream search.

LATERAL_START

public static final RollingLaneStructureRecord.RecordLink LATERAL_START

This record is laterally adjacent to the start distance source, and found in a downstream search.

CROSS

public static final RollingLaneStructureRecord.RecordLink CROSS

Part of the current cross-section.

Method Detail

values

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

Returns:

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

valueOf

public static RollingLaneStructureRecord.RecordLink 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

calculateStartDistance

public abstract Length calculateStartDistance(RollingLaneStructureRecord startDistanceSource,
                                              RollingLaneStructureRecord self,
                                              double fractionalPosition)

Calculate the start position of this record based on a neighboring source.

Parameters:

startDistanceSource - RollingLaneStructureRecord; source record in the tree

self - RollingLaneStructureRecord; own record

fractionalPosition - double; fractional position on the cross-section

Returns:

start position of this record based on a neighboring source
