java.lang.Enum<LineRelation>

org.kynosarges.tektosyne.geometry.LineRelation

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<LineRelation>

public enum LineRelation
extends java.lang.Enum<LineRelation>

Specifies the spatial relationship between two line segments.

Enum Constant Summary

Enum Constants

Enum Constant and Description
COLLINEAR Specifies that the two line segments are part of the same infinite line, and therefore may share some or all their points.
DIVERGENT Specifies that the two line segments have different angles, and therefore may share a single point of intersection.
PARALLEL Specifies that the two line segments are parallel displacements of each other, and therefore cannot share any points.

Method Summary

Modifier and Type	Method and Description
static LineRelation	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static LineRelation[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

PARALLEL

public static final LineRelation PARALLEL

Specifies that the two line segments are parallel displacements of each other, and therefore cannot share any points.

COLLINEAR

public static final LineRelation COLLINEAR

Specifies that the two line segments are part of the same infinite line, and therefore may share some or all their points.

DIVERGENT

public static final LineRelation DIVERGENT

Specifies that the two line segments have different angles, and therefore may share a single point of intersection.

Method Detail

values

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

Returns:

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

valueOf

public static LineRelation 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

java.lang.NullPointerException - if the argument is null
