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).

Member Function Documentation
template<typename Container> insert_iterator& std::insert_iterator< Container >::operator * () [inline]
Simply returns *this.
Definition at line 540 of file iterator.
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 iterator.
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 iterator.
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
