alib::enumops::BitwiseTraits< TEnum > Struct Template Reference

Description:

template<typename TEnum>
requires std::is_enum<TEnum>::value
struct alib::enumops::BitwiseTraits< TEnum >

Simple type trait that inherits std::false_type by default. If specialized for an enumeration type TEnum to inherit std::true_type, the following operators set of ALib operators become applicable to elements of TEnum:

• operator&
• operator&=
• operator|
• operator|=
• operator^
• operator^=
• operator~
• operator+ (Alias for operator|)
• operator- (Alias for a combination of operators operator& and operator~)
• operator+= (An alias for operator|=)
• operator-= (Removes given bit(s) )

Attention

Likewise with the operators introduced with the type trait ArithmeticalTraits, this documentation "fakes" the operators into namespace alib::enumops, while in fact they are defined in the global namespace.
See corresponding note in the Programmer's Manual for details.

Restrictions
For technical reasons, this concept is not applicable to enum types that are defined as private or protected inner types of structs or classes.

• For details and a source code sample see chapter 2.2 Bitwise Operators of the Programmer's Manual of the module ALib EnumOps.
