    - #### values

          public static DataType[] 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 (DataType c : DataType.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static DataType 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

    - #### getId

          public int getId()

      Specified by:
        `getId` in interface `OptionCodec.Codecable<DataType>`

    - #### readValue

          public java.lang.Object readValue(io.netty.buffer.ByteBuf cb,
                                   int version)

      Specified by:
        `readValue` in interface `OptionCodec.Codecable<DataType>`

    - #### writeValue

          public void writeValue(java.lang.Object value,
                        io.netty.buffer.ByteBuf cb,
                        int version)

      Specified by:
        `writeValue` in interface `OptionCodec.Codecable<DataType>`

    - #### serializedValueSize

          public int serializedValueSize(java.lang.Object value,
                                int version)

      Specified by:
        `serializedValueSize` in interface `OptionCodec.Codecable<DataType>`

    - #### fromType

          public static Pair<DataType,java.lang.Object> fromType(AbstractType type,
                                                 int version)
