`uds.utilities.enums`

Module with common and reused implementation of enums.

Enumerated types (enums) are data types that consists of named values. This module provides extension to aenum package.

Module Contents

`ExtendableEnum`	Enum that supports new members adding.
`ValidatedEnum`	Enum that supports members validation.
`ByteEnum`	Enum which members are one byte integers (0x00-0xFF) only.
`NibbleEnum`	Enum which members are one nibble (4 bits) integers (0x0-0xF) only.

class uds.utilities.enums.ExtendableEnum[source]

Bases: aenum.Enum

Enum that supports new members adding.

classmethod add_member(name, value)[source]

Register a new member.

Parameters:

Raises:

ValueError – Such name or value is already in use.

Returns:

The new member that was just created.

Return type:

aenum.Enum

class uds.utilities.enums.ValidatedEnum[source]

Bases: aenum.Enum

Enum that supports members validation.

classmethod is_member(value)[source]

Check whether given argument is a member or a value stored by this Enum.

Parameters:: value (Any) – Value to check.
Returns:: True if given argument is a member or a value of this Enum, else False.
Return type:: bool

classmethod validate_member(value)[source]

Validate whether given argument is a member or a value stored by this Enum.

Parameters:: value (Any) – Value to validate.
Raises:: ValueError – Provided value is not a member neither a value of this Enum.
Return type:: ValidatedEnum

class uds.utilities.enums.ByteEnum[source]

Bases: aenum.IntEnum

Initialize self. See help(type(self)) for accurate signature.

class uds.utilities.enums.NibbleEnum[source]

Bases: aenum.IntEnum

Enum which members are one nibble (4 bits) integers (0x0-0xF) only.

Initialize self. See help(type(self)) for accurate signature.
