Enum KeywordCase

  • All Implemented Interfaces:
    Serializable, Comparable<Keyword­Case>

    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
    Note: Well-Known Text keywords are case insensitive at parsing time. KEYWORD is equivalent to keyword is equivalent to Key­Word and to k­EYw­ORd.

    • Enum Constant Detail

      • 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 Detail

      • values

        public static KeywordCase[] 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 (KeywordCase c : KeywordCase.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static KeywordCase 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
