allow_bitmask_type

allow_bitmask_type : bool = True

If set to true, allow enum/enum class as operands to arithmetic operators if they satisfy the "BitmaskType" concept. Note: The Axivion Suite does not detect if a class actually satisfy the "BitmaskType" concept, please refer to the option fully_qualified_bitmask_types.

 

fully_qualified_bitmask_types

fully_qualified_bitmask_types

Type: set[bauhaus.analysis.config.QualifiedName]

Default: {'std::_Codecvt_mode', 'std::_Iosb::_Fmtflags', 'std::_Iosb::_Iostate', 'std::_Iosb::_Openmode', 'std::ctype_base::mask', 'std::filesystem::copy_options', 'std::filesystem::directory_options', 'std::filesystem::perms', 'std::ios_base::fmtflags', 'std::ios_base::iostate', 'std::ios_base::openmode', 'std::launch', 'std::regex_constants::match_flag_type', 'std::regex_constants::syntax_option_type', 'std::regex_traits::char_class_type'}

A set of fully qualified types that satisfy the "BitmaskType" concept. This has no effect if allow_bitmask_type is not enabled.

 

report_use_in_operator_calls

report_use_in_operator_calls : bool = True

Whether enum arguments in calls to forbidden overloaded operators should be reported.
