🔗
const T& operator*() const;
1
#
Preconditions: in_­stream != nullptr is true.
2
#
Returns: value.
🔗
const T* operator->() const;
3
#
Preconditions: in_­stream != nullptr is true.
4
#
Returns: addressof(value).
🔗
istream_iterator& operator++();
5
#
Preconditions: in_­stream != nullptr is true.
6
#
Effects: Equivalent to: 
if (!(*in_stream >> value))
  in_stream = nullptr;
7
#
Returns: *this.
🔗
istream_iterator operator++(int);
8
#
Preconditions: in_­stream != nullptr is true.
9
#
Effects: Equivalent to: 
istream_iterator tmp = *this;
++*this;
return tmp;
🔗
template<class T, class charT, class traits, class Distance> bool operator==(const istream_iterator<T,charT,traits,Distance>& x, const istream_iterator<T,charT,traits,Distance>& y);
10
#
Returns: x.in_­stream == y.in_­stream.
🔗
friend bool operator==(const istream_iterator& i, default_sentinel_t);
11
#
Returns: !i.in_­stream.
