std::is_aggregate

STD：：是[医]骨料

Defined in header ​​
template< class T > struct is_aggregate;​(since C++17)

检查T是集料类型.成员常量value等于true如果T是一个聚合类型，并且false否则。

如果std::remove_all_extents_t<T>是%28以外的不完整类型(可能是cv-合格%29)。void...

模板参数

T-a type to check

辅助变量模板

template< class T > inline constexpr bool is_aggregate_v = std::is_aggregate::value;​(since C++17)

继承自STD：积分[医]常量

成员常数

value statictrue if T is an aggregate type , false otherwise (public static member constant)

成员函数

operator boolconverts the object to bool, returns value (public member function)
operator() (C++14)returns value (public member function)

成员类型
