Radius Attribute Datatypes

class chewie.radius_datatypes.Concat(bytes_data=None, raw_data=None)

Bases: DataType

AttributeTypes that use Concat must override their pack()

DATA_TYPE_VALUE = 6

data()

Subclass should override this as needed. Returns:

The python type (int, str, bytes) of the bytes_data.

This will perform any decoding as required instead of using the unprocessed bytes_data.

data_length()

Returns:

length of the data field, and not total length of the attribute (including the

type and length).

If total is required use full_length.

full_length()

Returns:

Length of the whole field include the header (type and length)

pack(attribute_type)

classmethod parse(packed_value)

class chewie.radius_datatypes.DataType

Bases: object

Parent datatype class, subclass should provide implementation for abstractmethods. May
