Enum LuceneFunction

  • All Implemented Interfaces:
    Serializable, Comparable<LuceneFunction>

    public enum LuceneFunction
    extends Enum<LuceneFunction>
    Functions that can be applied to lucene fields Currently upper and lower that perform a case insensitive match for untokenised fields. (If the field is tokenised the match should already be case insensitive.)

      • values

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

        public static LuceneFunction 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
