    • Enum Constant Detail

      • INNER

        public static final JoinType INNER
        Use an inner join, ie. only select rows present in both tables.
      • LEFT

        public static final JoinType LEFT
        Use a left join, ie. select all rows from the left table and use null if no row is present in the right table.

      • joinExpression

        private final String joinExpression
    • Constructor Detail

      • JoinType

        private JoinType​(String joinExpression)
    • Method Detail

      • values

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

        public static JoinType 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
