std::pointer_to_binary_function

STD：：指针[医]到[医]二进制[医]功能

template< class Arg1, class Arg2, class Result > class pointer_to_binary_function : public std::binary_function;​(until C++17)(deprecated since C++11)

std::pointer_to_binary_function函数对象，充当二进制函数的包装器。

成员函数

(constructor)constructs a new pointer_to_binary_function object with the supplied function (public member function)
operator()calls the stored function (public member function)

STD：：指针[医]到[医]二进制[医]功能：指针[医]到[医]二进制[医]功能

explicit pointer_to_binary_function( Result (*f)(Arg1,Arg2) ​​

构造一个pointer_to_binary_function具有存储函数的函数对象。f...

参数

f-pointer to a function to store

STD：：指针[医]到[医]二进制[医]功能：操作员%28%29

Result operator()( Arg1 x1, Arg2 x2 ) const;​​

调用存储函数。

参数

x1, x2-arguments to pass to the function

返回值

被调用的函数返回的值。

另见

pointer_to_unary_function (until C++17)adaptor-compatible wrapper for a pointer to unary function (class template)
ptr_fun (until C++17)creates an adaptor-compatible function object wrapper from a pointer to function (function template)
