NAME

std::istream_iterator< _Tp, _CharT, _Traits, _Dist > - Provides input iterator semantics for streams.

SYNOPSIS

#include <iterator>

Inherits std::iterator< input_iterator_tag, _Tp, ptrdiff_t, const _Tp *, const _Tp & >.

Public Types


typedef _CharT char_type
typedef ptrdiff_t difference_type
Distance between iterators is represented as this type. typedef basic_istream< _CharT, _Traits > istream_type
typedef input_iterator_tag iterator_category
One of the tag types. typedef const _Tp * pointer
This type represents a pointer-to-value_type. typedef const _Tp & reference
This type represents a reference-to-value_type. typedef _Traits traits_type
typedef _Tp value_type
The type 'pointed to' by the iterator.
