      • NUMERIC

        public static final Attribute.Type NUMERIC
        Numeric attribute.
      • NOMINAL

        public static final Attribute.Type NOMINAL
        Nominal attribute. Variables assessed on a nominal scale are called categorical variables.
      • STRING

        public static final Attribute.Type STRING
        String attribute. Note that strings should not be treated as nominal attribute because one may use some part of strings (e.g. suffix or prefix) instead of the original string as features.
      • DATE

        public static final Attribute.Type DATE
        Date attribute. A date type also optionally specifies the format in which the date is presented, with the default being in ISO-8601 format.
    • Method Detail

      • values

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

        public static Attribute.Type valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
