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 >
constexpr TEnum	operator+ (TEnum element, int addend) noexcept(true)
template<typename TEnum >
constexpr TEnum	operator- (TEnum element, int subtrahend) noexcept(true)

Function Details:

operator+()

template<typename TEnum >

constexpr TEnum operator+ ( TEnum element, int addend )

constexprnoexcept

Add operator useable 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.

Parameters

element	First operand of TEnum type.
addend	The addend as of int type.

Returns

The "addend-th" enum element after element .

operator-()

template<typename TEnum >

constexpr TEnum operator- ( TEnum element, int subtrahend )

constexprnoexcept

Subtract operator useable 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.

Parameters

element	First operand of TEnum type.
subtrahend	The subtrahend as of int type.

Returns

The "subtrahend-th" enum element before element .
