Detailed Description

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

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 480 of file stl_iterator.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).

Member Function Documentation

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

Simply returns *this.

Definition at line 522 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 530 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 526 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
