NAME¶
std::istream_iterator< _Tp, _CharT, _Traits, _Dist > - Provides input iterator semantics for streams.
SYNOPSIS¶
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.
Public Member Functions¶
constexpr istream_iterator ()
Construct end of input stream iterator. istream_iterator (const
istream_iterator &__obj)
istream_iterator (istream_type &__s)
Construct start of input stream iterator. const _Tp & operator* ()
const
istream_iterator & operator++ ()
istream_iterator operator++ (int)
const _Tp * operator-> () const
istream_iterator & operator= (const istream_iterator
&)=default
Friends¶
bool operator!= (const istream_iterator &__x,
const istream_iterator &__y)
Return true if the iterators refer to different streams, or if one is at
end-of-stream and the other is not. bool operator== (const
istream_iterator &__x, const istream_iterator &__y)
Return true if the iterators refer to the same stream, or are both at
end-of-stream.
