vector<int> V; copy(istream_iterator<int>(cin), istream_iterator<int>(), back_inserter(V));
Parameter | Description | Default |
---|---|---|
T | The istream_iterator's value type. Operator* returns a const T&. | |
Distance | The istream_iterator's distance type. | ptrdiff_t |
The value type T must be a model of Default Constructible.
The distance type must, as described in the Input Iterator requirements, be a signed integral type.
Member | Where defined | Description |
---|---|---|
istream_iterator() | istream_iterator | See below. |
istream_iterator(istream&) | istream_iterator | See below. |
istream_iterator(const istream_iterator&) | Trivial Iterator | The copy constructor |
istream_iterator& operator=(const istream_iterator&) | Trivial Iterator | The assignment operator |
const T& operator*() const | Input Iterator | Returns the next object in the stream. |
istream_iterator& operator++() | Input Iterator | Preincrement. |
istream_iterator& operator++(int) | Input Iterator | Postincrement. |
bool operator==(const istream_iterator&, const istream_iterator&) | Trivial iterator | The equality operator. This is a global function, not a member function. |
input_iterator_tag iterator_category(const istream_iterator&) | iterator tags | Returns the iterator's category. |
T* value_type(const istream_iterator&) | iterator tags | Returns the iterator's value type. |
Distance* distance_type(const istream_iterator&) | iterator tags | Returns the iterator's distance type. < |
Function | Description |
---|---|
istream_iterator() | The default constructor: Constructs an end-of-stream iterator. This is a past-the-end iterator, and it is useful when constructing a "range". |
istream_iterator(istream& s) | Creates an istream_iterator that reads values from the input stream s. When s reaches end of stream, this iterator will compare equal to an end-of-stream iterator created using the default constructor. |
