27.6.1 Class template istream_­iterator [istream.iterator]

27.6.1.2 istream_­iterator operations [istream.iterator.ops]

const T& operator*() const;
Returns: value.
const T* operator->() const;
Returns: addressof(operator*()).
istream_iterator& operator++();
Requires: in_­stream != 0.
Effects: As if by: *in_­stream >> value;
Returns: *this.
istream_iterator operator++(int);
Requires: in_­stream != 0.
Effects: As if by:
istream_iterator tmp = *this;
*in_stream >> value;
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);
Returns: x.in_­stream == y.in_­stream.
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);
Returns: !(x == y)
