std::greater_equal
STD：：更大[医]平等
| Defined in header | | |
|---|---|---|
| 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 | (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 | greater_equal | 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；}
