NAME¶
std::istream_iterator< _Tp, _CharT, _Traits, _Dist > - Provides input iterator semantics for streams.
SYNOPSIS¶
#include <iterator>
Inherits std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >.
Public Types¶
typedef _CharT char_type
typedef _Distance difference_type
Distance between iterators is represented as this type. typedef
basic_istream< _CharT, _Traits > istream_type
typedef _Category iterator_category
One of the tag types. typedef _Pointer pointer
This type represents a pointer-to-value_type. typedef _Reference
reference
This type represents a reference-to-value_type. typedef _Traits
traits_type
typedef _Tp value_type
The type 'pointed to' by the iterator.
