        Description copied from interface: DataType
        Encode bytes from an Object appropriate for this DataType.

        Converts the given object to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the object may come from a user script. For example, a floating-point value may be rounded. Invalid values should be rejected with a DataTypeEncodeException.

        Specified by:
        encodeValue in interface DataType
        Overrides:
        encodeValue in class AbstractDataType
        Parameters:
        value - the desired value.
        buf - a buffer representing the eventual destination of the bytes.
        settings - the settings to use.
        length - the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.
        Returns:
        the encoded value.
        Throws:
        DataTypeEncodeException - if the value cannot be encoded for any reason, e.g., incorrect type, not enough space, buffer overflow, unsupported (see DataType.isEncodable()).

        Description copied from interface: DataType
        Encode bytes according to the display format for this type.

        Converts the given representation to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the representation is likely coming from user input. For example, a floating-point value may be rounded. Invalid representations should be rejected with a DataTypeEncodeException.

        Specified by:
        encodeRepresentation in interface DataType
        Overrides:
        encodeRepresentation in class AbstractDataType
        Parameters:
        repr - the representation of the desired value, as in DataType.getRepresentation(MemBuffer, Settings, int). The supported formats depend on the specific datatype and its settings.
        buf - a buffer representing the eventual destination of the bytes.
        settings - the settings to use for the representation.
        length - the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.
        Returns:
        the encoded value.
        Throws:
        DataTypeEncodeException - if the value cannot be encoded for any reason, e.g., incorrect format, not enough space, buffer overflow, unsupported (see DataType.isEncodable()).
