alib::enums::iterable Namespace Reference

Description:

Operators available to elements of enumerations if T_EnumIsIterable is specialized.

Note

This namespace exits only in the documentation to collect the operators. When parsed by a C++ compiler, the operators reside in the global namespace.

Function Index:
template<typename TEnum , typename TRhs = int>
constexpr TEnum	operator+ (TEnum element, TRhs summand) noexcept
template<typename TEnum , typename TRhs = int>
constexpr TEnum	operator- (TEnum element, TRhs subtrahend) noexcept

Function Details:

operator+()

template<typename TEnum , typename TRhs = int>

TEnum operator+ ( TEnum element, TRhs summand )

constexprnoexcept

Add operator usable with scoped enum types and integral values.

Selected by the compiler only if T_EnumIsIterable is specialized for enum type TEnum.

Template Parameters

TEnum	Enumeration type.
TRhs	The type of the summand.

Parameters

element	First operand of TEnum type.
summand	The summand.

Returns

The "summand-th" enum element after element .

operator-()

template<typename TEnum , typename TRhs = int>

TEnum operator- ( TEnum element, TRhs subtrahend )

constexprnoexcept

Subtract operator usable with scoped enum types and integral values.

Selected by the compiler only if T_EnumIsIterable is specialized for enum type TEnum.

Template Parameters

TEnum	Enumeration type.
TRhs	The type of the subtrahend.

Parameters

element	First operand of TEnum type.
subtrahend	The subtrahend.

Returns

The "subtrahend-th" enum element before element .
