std::rel_ops - Man Page
The generated relational operators are sequestered here.
Synopsis
Functions
template<class _Tp > bool operator!= (const _Tp &__x, const _Tp &__y)
Defines != for arbitrary types, in terms of ==.
template<class _Tp > bool operator<= (const _Tp &__x, const _Tp &__y)
Defines <= for arbitrary types, in terms of <.
template<class _Tp > bool operator> (const _Tp &__x, const _Tp &__y)
Defines > for arbitrary types, in terms of <.
template<class _Tp > bool operator>= (const _Tp &__x, const _Tp &__y)
Defines >= for arbitrary types, in terms of <.
Detailed Description
The generated relational operators are sequestered here.
Libstdc++ headers must not use the contents of rel_ops. User code should also avoid them, because unconstrained function templates are too greedy and can easily cause ambiguities.
C++20 default comparisons are a better solution.
Function Documentation
template<class _Tp > bool std::rel_ops::operator!= (const _Tp & __x, const _Tp & __y) [inline]
Defines != for arbitrary types, in terms of ==.
Parameters
__x A thing.
__y Another thing.
Returns
__x != __y
This function uses == to determine its result.
template<class _Tp > bool std::rel_ops::operator<= (const _Tp & __x, const _Tp & __y) [inline]
Defines <= for arbitrary types, in terms of <.
Parameters
__x A thing.
__y Another thing.
Returns
__x <= __y
This function uses < to determine its result.
template<class _Tp > bool std::rel_ops::operator> (const _Tp & __x, const _Tp & __y) [inline]
Defines > for arbitrary types, in terms of <.
Parameters
__x A thing.
__y Another thing.
Returns
__x > __y
This function uses < to determine its result.
template<class _Tp > bool std::rel_ops::operator>= (const _Tp & __x, const _Tp & __y) [inline]
Defines >= for arbitrary types, in terms of <.
Parameters
__x A thing.
__y Another thing.
Returns
__x >= __y
This function uses < to determine its result.
