NAME
std::insert_iterator -SYNOPSIS
Inherits std::iterator< std::output_iterator_tag, void, void, void, void >.
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 547 of file stl_iterator.h.
template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&> typedef _Distance std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::difference_type [inherited]
Distance between iterators is represented as this type.
Reimplemented in std::reverse_iterator< _Iterator >.
Definition at line 113 of file stl_iterator_base_types.h.
template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&> typedef _Category std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::iterator_category [inherited]
One of the tag types.
Definition at line 109 of file stl_iterator_base_types.h.
template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&> typedef _Pointer std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::pointer [inherited]
This type represents a pointer-to-value_type.
Reimplemented in std::reverse_iterator< _Iterator >.
Definition at line 115 of file stl_iterator_base_types.h.
template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&> typedef _Reference std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::reference [inherited]
This type represents a reference-to-value_type.
Reimplemented in std::reverse_iterator< _Iterator >.
Definition at line 117 of file stl_iterator_base_types.h.
template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&> typedef _Tp std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::value_type [inherited]
The type 'pointed to' by the iterator.
Definition at line 111 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 553 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 589 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 599 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 594 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
