Description:

template<typename TEnum, typename TEnableIf>
struct alib::enums::T_EnumIsBitwise< TEnum, TEnableIf >

Simple TMP struct 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 TMP struct T_EnumIsArithmetical , this documentation "fakes" the operators into namespace alib::enums, 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.

Template Parameters

TEnum	The enum type to enable arithmetical operators for.
TEnableIf	This parameter has a default expressions and must not be provided with specializations of this struct. It is used to ensure that template parameter TEnum is an enumeration type.
