c++ - 将成员函数指针传递给模板函数

Question

我正在尝试传递一个类成员函数指针

template < typename CLASS, typename TYPE1, typename TYPE2 > 
  void WriteFunctionHelper(CLASS* pOwner, PropInfoType::iterator& it, WriterPtr pw, WriterPtr (Writer::*func)(TYPE1, TYPE2) ) {
     MemberProperty<CLASS,TYPE2> *ptr = (MemberProperty<CLASS, TYPE2> *)it->second;
     const char *propertName = ptr->m_propertyName.c_str(); 
      if ( !ptr->m_getterFn ) { 
        throw; 
      } 
      pw->*func(propertName,(pOwner->*(ptr->m_getterFn))()); 
  }

我收到编译器错误 error C2064: term does not evaluate to a function taking 2 arguments 我在做什么错了

Answer 1

在 pw->*func 周围添加括号

(pw->*func)(propertName,(pOwner->*(ptr->m_getterFn))());
