std::greater_equal
| Defined in header <functional> |  |  | 
|---|---|---|
| template< class T > struct greater_equal; |  | (until C++14) | 
| template< class T = void > struct greater_equal; |  | (since C++14) | 
用于执行比较的函数对象。除非专门化,否则调用operator>=论类型T...
专门性
...的专业化std::greater_equal对于任何指针类型,都会产生严格的总顺序,即使内置operator<=不会的。严格的全序在专业之间是一致的。std::less,,,std::greater,,,std::less_equal,和std::greater_equal对于该指针类型,并且与相应的内建运算符%28施加的偏序一致。<,,,>,,,<=和>=29%。
| If the function call operator of the specialization std::greater_equal<void> calls a built-in operator comparing pointers, it yields a strict total order even if the built-in operator<= does not.This strict total order is consistent among the specializations std::less<void>, std::greater<void>, std::less_equal<void>, and std::greater_equal<void>, and is also consistent with the partial order imposed by the corresponding built-in operators. | (since C++14) | 
|---|
| The standard library provides a specialization of std::greater_equal when T is not specified, which leaves the parameter types and return type to be deduced. greater_equal<void> function object implementing x >= y deducing argument and return types (class template specialization) | greater_equal<void> | function object implementing x >= y deducing argument and return types (class template specialization) | (since C++14) | 
|---|---|---|---|
| greater_equal<void> | function object implementing x >= y deducing argument and return types (class template specialization) | 
成员类型
| type | definition | 
|---|---|
| result_type(deprecated in C++17) | bool | 
| first_argument_type(deprecated in C++17) | T | 
| second_argument_type(deprecated in C++17) | T | 
成员函数
| operator() | checks if the first argument is greater than or equal to the second (public member function) |

STD::更大[医]相等::运算符%28%29
| bool operator()( const T& lhs, const T& rhs ) const; |  | (until C++14) | 
|---|---|---|
| constexpr bool operator()( const T& lhs, const T& rhs ) const; |  | (since C++14) | 
检查是否lhs是更大比或平等到rhs...
参数
| lhs, rhs | - | values to compare | 
|---|
返回值
true如果lhs >= rhs,,,false否则。
例外
%280%29
可能的实施
Const T&LHS,Const T&RHS%29 Const{RHS>=rhs;}
