istream_iterator::~istream_iterator

istream_iterator::operator*istream_iterator::operator->

istream_iterator::operator++istream_iterator::operator++(int)

非成员函数

operator==operator!= (C++20 前)

 

~istream_iterator();		(C++11 前)
~istream_iterator() = default;		(C++11 起)

销毁迭代器，包含缓冲的值。

若 std::is_trivially_destructible<T>::value 为 true ，则此析构函数为平凡析构函数。

(C++11 起)
