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.

Member Typedef Documentation
template<typename _Container> typedef _Container std::insert_iterator< _Container >::container_type
A nested typedef for the type of whatever container you used.
Definition at line 596 of file stl_iterator.h.
typedef void std::iterator< output_iterator_tag , void , void , void , void >::difference_type [inherited]
Distance between iterators is represented as this type.
Definition at line 125 of file stl_iterator_base_types.h.
typedef output_iterator_tag std::iterator< output_iterator_tag , void , void , void , void >::iterator_category [inherited]
One of the tag types.
Definition at line 121 of file stl_iterator_base_types.h.
typedef void std::iterator< output_iterator_tag , void , void , void , void >::pointer [inherited]
This type represents a pointer-to-value_type.
Definition at line 127 of file stl_iterator_base_types.h.
typedef void std::iterator< output_iterator_tag , void , void , void , void >::reference [inherited]
This type represents a reference-to-value_type.
Definition at line 129 of file stl_iterator_base_types.h.
typedef void std::iterator< output_iterator_tag , void , void , void , void >::value_type [inherited]
The type 'pointed to' by the iterator.
Definition at line 123 of file stl_iterator_base_types.h.
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 602 of file stl_iterator.h.
Member Function Documentation
template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator* () [inline]
Simply returns *this.
Definition at line 656 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 661 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 666 of file stl_iterator.h.
template<typename _Container> insert_iterator& std::insert_iterator< _Container >::operator= (const typename _Container::value_type &__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
*
