Detailed Description

template<typename _Container>
class std::insert_iterator< _Container >

Turns assignment into insertion.

These are output iterators, constructed from a container-of-T. Assigning a T to the iterator inserts it in the container at the iterator's position, rather than overwriting the value at that position.

(Sequences will actually insert a copy of the value before the iterator's position.)

Tip: Using the inserter function to create these iterators can save typing.

Constructor & Destructor Documentation

template<typename _Container> std::insert_iterator< _Container >::insert_iterator (  _Container &  __x, typename _Container::iterator  __i )  [inline]

The only way to create this iterator is with a container and an initial position (a normal iterator into the container). Definition at line 504 of file stl_iterator.h. References std::insert_iterator< _Container >::iter.

Member Function Documentation

template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator * (   )  [inline]

Simply returns *this. Definition at line 540 of file stl_iterator.h.

template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator++ (  int   )  [inline]

Simply returns *this. (This iterator does not "move".). Definition at line 550 of file stl_iterator.h.

template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator++ (   )  [inline]

Simply returns *this. (This iterator does not "move".). Definition at line 545 of file stl_iterator.h.

template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator= (  const typename _Container::const_reference  __value  )  [inline]

Parameters: value  An instance of whatever type container_type::const_reference is; presumably a reference-to-const T for container<T>. Returns: This iterator, for chained operations. This kind of iterator maintains its own position in the container. Assigning a value to the iterator will insert the value into the container at the place before the iterator. The position is maintained such that subsequent assignments will insert values immediately after one another. For example, // vector v contains A and Z insert_iterator i (v, ++v.begin()); i = 1; i = 2; i = 3; // vector v contains A, 1, 2, 3, and Z Definition at line 531 of file stl_iterator.h.
