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 498 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 113 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 109 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 115 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 117 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 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 504 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 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.
