Enum DatelineRule

java.lang.Object

java.lang.Enum<DatelineRule>

com.spatial4j.core.context.jts.DatelineRule

All Implemented Interfaces:

Serializable, Comparable<DatelineRule>

public enum DatelineRule
extends Enum<DatelineRule>

Indicates the algorithm used to process JTS Polygons and JTS LineStrings for detecting dateline crossings. It only applies when geo=true.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ccwRect For rectangular polygons, the point order is interpreted as being counter-clockwise (CCW).
none No polygon will cross the dateline.
width180 Adjacent points with an x (longitude) difference that spans more than half way around the globe will be interpreted as going the other (shorter) way, and thus cross the dateline.

Enum Constant Detail

none

public static final DatelineRule none

No polygon will cross the dateline.

width180

public static final DatelineRule width180

Adjacent points with an x (longitude) difference that spans more than half way around the globe will be interpreted as going the other (shorter) way, and thus cross the dateline.

ccwRect

public static final DatelineRule ccwRect

For rectangular polygons, the point order is interpreted as being counter-clockwise (CCW). However, non-rectangular polygons or other shapes aren't processed this way; they use the width180 rule instead. The CCW rule is specified by OGC Simple Features Specification v. 1.2.0 section 6.1.11.1.

Method Detail

values

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

Returns:

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

valueOf

public static DatelineRule 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
