Enum Class KeywordCase

Object
Enum<KeywordCase>
KeywordCase
All Implemented Interfaces:
Serializable, Comparable<Keyword­Case>, Constable
public enum KeywordCase extends Enum<KeywordCase>
Whether WKT keywords shall be written with lower, upper or camel case styles. The most common usage for WKT keywords is upper case. However, with version 2 of Well Known Text, camel case keywords may be easier to read because WKT 2 has more keywords made by combination of words. Examples:
WKT element case comparisons
Upper case Camel case
TIMEEXTENT TimeExtent
ANGLEUNIT AngleUnit
BASEGEODCRS BaseGeodCRS
DERIVINGCONVERSION DerivingConversion
ENGINEERINGDATUM EngineeringDatum
Well-Known Text keywords are case insensitive at parsing time. KEYWORD is equivalent to keyword is equivalent to Key­Word and to k­EYw­ORd.

  • Enum Constant Details

    • LOWER_CASE

      public static final KeywordCase LOWER_CASE
      WKT formatting uses lower case keywords.

    • UPPER_CASE

      public static final KeywordCase UPPER_CASE
      WKT formatting uses upper case keywords. This is the most usual case in WKT 1 strings.

    • CAMEL_CASE

      public static final KeywordCase CAMEL_CASE
      WKT formatting uses CamelCase keywords. This is more useful in WKT 2 strings, which use longer keywords than WKT 1 did. Examples: "Time­Extent", "Angle­Unit".

    • DEFAULT

      public static final KeywordCase DEFAULT
      Keywords case is determined by the WKT convention. The current mapping is:
      • Well Known Text version 2 uses camel case.
      • Well Known Text version 1 uses upper case.

  • Method Details

    • values

      public static KeywordCase[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static KeywordCase valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      Null­Pointer­Exception - if the argument is null
