otupy.profiles.slpf.data.direction.Direction

class Direction(value=<no_arg>, names=None, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enumerated

Direction enumeration

The packet direction to which a rule applies. Defined in Sec. 2.1.3.2 of the SLPF Specification.

Methods

extend	Extends the Enumarated
todict	Converts to dictionary
fromdict	Builds instance from dictionary

Attributes

both	Apply rules to all traffic
ingress	Apply rules to incoming traffic only
egress	Apply rules to outgoing traffic only

__init__(*args, **kwds)

both = 1

Apply rules to all traffic

egress = 3

Apply rules to outgoing traffic only

classmethod extend(name, value=None)

Extends the Enumarated

Extends the definition with a new <name, value> pair.

Parameters:

• name – The name (tag) used to identify a new element in the Enumeration.

• value – The numeric index associated to the Enumerated (optional).

Returns:

None

classmethod fromdict(dic, e)

Builds instance from dictionary

It is used during deserialization to create an otupy instance from the text message. It takes an Encoder instance that is used to recursively build instances of the inner objects (the Encoder provides standard methods to create instances of base objects like strings, integers, boolean).

Parameters:

• dic – The intermediary dictionary representation from which the object is built.

• e – The Encoder that is being used.

Returns:

An instance of this class initialized from the dictionary values.

ingress = 2

Apply rules to incoming traffic only

todict(e)

Converts to dictionary

It is used to convert this object to an intermediary representation during serialization. It takes an Encoder argument that is used to recursively serialize inner data and structures (the Encoder provides standard methods for converting base types to dictionaries)..

Parameters:

e – The Encoder that is being used.

Returns:

A dictionary compliants to the Language Specification’s serialization rules.
