mem_fun1_t 클래스

이항 함수 개체로 호출되어 포인터 인수를 사용하여 초기화될 때 하나의 인수를 취하는 non_const 멤버 함수를 사용할 수 있는 어댑터 클래스

template<class Result, class Type, class Arg>
   class mem_fun1_t : public binary_function<Type *, Arg, Result> {
      explicit mem_fun1_t(
         Result (Type::* _Pm )( Arg ) 
         );
      Result operator()(
         Type* _Pleft, 
         Arg _Right
         ) const;
   };

매개 변수

• _Pm
  A pointer to the member function of class Type to be converted to a function object.

• _Pleft
  The object that the _Pm member function is called on.

• _Right
  The argument that is being given to _Pm.

반환 값

An adaptable binary function.

설명

The template class stores a copy of _Pm, which must be a pointer to a member function of class Type, in a private member object. It defines its member function operator() as returning (_Pleft->* _Pm)(_Right).

예제

The constructor of mem_fun1_t is not usually used directly; the helper function mem_fun is used to adapt member functions. See mem_fun for an example of how to use member function adaptors.
