std::greater_equal(3) C++ Standard Libary std::greater_equal(3) NAME std::greater_equal - std::greater_equal Synopsis Defined in header <functional> template< class T > (until C++14) struct greater_equal; template< class T = void > (since C++14) struct greater_equal; Function object for performing comparisons. The main template in- vokes operator>= on type T. Specializations greater_equal<void> function object implementing x >= y deducing pa- rameter and (C++14) return types (class template specialization) Member types Type Defini- tion result_type (deprecated in C++17)(removed in C++20) bool first_argument_type (deprecated in C++17)(removed in C++20) T second_argument_type (deprecated in C++17)(removed in C++20) T These member types are obtained via publicly inheriting (until C++11) std::binary_function<T, T, bool>. Member functions operator() checks if the first argument is greater than or equal to the second (public member function) std::greater_equal::operator() bool operator()( const T& lhs, const T& rhs ) const; (un- til C++14) constexpr bool operator()( const T& lhs, const T& rhs ) const; (since C++14) Checks whether lhs is greater than or equal to rhs. Parameters lhs, rhs - values to compare Return value lhs >= rhs. If T is a pointer type, the result is consistent with the implemen- tation-defined strict total order over pointers. Exceptions May throw implementation-defined exceptions. Possible implementation constexpr bool operator()(const T& lhs, const T& rhs) const { return lhs >= rhs; // assumes that the implementation handles pointer total order } Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Cor- rect behavior LWG 2562 C++98 the pointer total order might be guaranteed to be consistent inconsistent See also less function object implementing x < y (class template) ranges::greater_equal constrained function object implementing x >= y (C++20) (class) http://cppreference.com 2024.06.10 std::greater_equal(3)
