template<classTy>structis_member_function_pointer; 参数 Ty 要查询的类型。 备注 如果类型 Ty是指向成员函数的指针或指向成员函数的cv-qualified指针,类型谓词的实例将为 true,否则为 false。 示例 C++ // std__type_traits__is_member_function_pointer.cpp// compile with: /EHsc#include<type_traits>#inclu...

std::is_member_function_pointer is a UnaryTypeTrait. Checks whether T is a non-static member function pointer. Provides the member constant value which is equal to true, if T is a non-static member function pointer type. Otherwise, value is equal to false. If the program adds ...
语法 C++ 复制 HRESULT get_isPointerToMemberFunction( BOOL* pRetVal); 参数 pRetVal [out] 指向指定此符号是否是指向成员函数的指针的 BOOL 的指针。 返回值 如果成功,则返回 S_OK;否则,返回 S_FALSE 或错误代码。 另请参阅 IDiaSymbol 反馈 此页面是否有帮助? 是 否 中文...

std :: is_member_function_pointer是C++标准库中的Type Trait之一,可用于检查给定类型是否是成员函数指针类型。它的定义如下: template<class T> struct is_member_function_pointer; 如果T是成员函数指针类型,则is_member_function_pointer的值为true,否则为false。

The template argument to function is for a function that takes two parameters by value. Your member function takes two arguments by non-const reference. You need to change at least the template argument to: typedef std::function<void(entityx::Entity&, OutputArchive&) func...
