我正在尝试在我正在创建的模板类中创建一个向量迭代器。以下是故障码。
void editor<T>::insert()
{
typedef typename std::vector<T>::const_iterator itr;
itr it;
it = this->buffer.begin();
for(int i = 0; i < line_num -1; ++i)
{
++it;
}
this->buffer.insert(it, user_text);
std::cout << "Cool, Your new line has been inserted." << '\n';
}
std::cout << '\n';
}
我收到以下编译错误:
error: no match for ‘operator=’ in ‘it = ((editor<std::basic_string<char> >*)this)->editor<std::basic_string<char> >::buffer.std::vector<_Tp, _Alloc>::begin [with _Tp = std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > >, _Alloc = std::allocator<std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > > >, std::vector<_Tp, _Alloc>::iterator = __gnu_cxx::__normal_iterator<std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > >*, std::vector<std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > >, std::allocator<std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > > > > >, typename std::_Vector_base<_Tp, _Alloc>::_Tp_alloc_type::pointer = std::vector<std::basic_string<char>, std::allocator<std::basic_string<char> > >*]()’
我感觉编译器对我typedef
上面的陈述感到困惑,但这就是我所看到的声明正确迭代器的方式,但由于某种原因它无法正常工作。有任何想法吗?
