Enum IgnoreNullsMode

  • All Implemented Interfaces:
    Serializable, Comparable<IgnoreNullsMode>

    public enum IgnoreNullsMode
    extends Enum<IgnoreNullsMode>

    The SCALAR_ONLY mode supports updates to scalar attributes to any level (top level, first nested level, second nested level, etc.) when the user wants to update scalar attributes by providing only the delta of changes to be updated. This mode does not support updates to maps and is expected to throw a 4xx DynamoDB exception if done so.

    In the MAPS_ONLY mode, creation of new map/bean structures through update statements are supported, i.e. setting null/non-existent maps to non-null values. If users try to update scalar attributes in this mode, it will overwrite existing values in the table.

    The DEFAULT mode disables any special handling around null values in the update query expression

      • values

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

        public static IgnoreNullsMode 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
