public enum DatelineRule extends Enum<DatelineRule>
Indicates the algorithm used to process JTS Polygons and JTS LineStrings for detecting dateline (aka anti-meridian) crossings. It only applies when geo=true.

Enum Constant Summary
Enum Constants Enum Constant 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 thewidth180
rule instead. The CCW rule is specified by OGC Simple Features Specification v. 1.2.0 section 6.1.11.1.

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 nameNullPointerException
- if the argument is null
