These classes override how a class's attributes are get/set/deleted. This is how the @property decorator works.

Keyword Parameters: name_regex The name of instance's regex setting attribute; used as name_regex below. If unset, regular expressions will never be used. lookup_function The name of the SELinuxPolicy lookup function, e.g. lookup_type or lookup_boolean. default_value The default value of the criteria. The default is None. enum_class The class of enumeration which supports a lookup class method. Read-only instance attribute use (obj parameter): policy The instance of SELinuxPolicy name_regex This attribute is read to determine if the criteria should be looked up or compiled into a regex. If the attribute does not exist, False is assumed.
