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

typedef Container container_type
 

A nested typedef for the type of whatever container you used.

Definition at line 509 of file stl_iterator.h.

typedef 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 iterator_category [inherited]
 

One of the tag types.

Definition at line 109 of file stl_iterator_base_types.h.

typedef void pointer [inherited]
 

This type represents a pointer-to-value_type.

Definition at line 115 of file stl_iterator_base_types.h.

typedef void reference [inherited]
 

This type represents a reference-to-value_type.

Definition at line 117 of file stl_iterator_base_types.h.

typedef 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

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 515 of file stl_iterator.h.


Member Function Documentation

insert_iterator& operator *  )  [inline]
 

Simply returns *this.

Definition at line 551 of file stl_iterator.h.

insert_iterator& operator++ int   )  [inline]
 

Simply returns *this. (This iterator does not "move".).

Definition at line 561 of file stl_iterator.h.

insert_iterator& operator++  )  [inline]
 

Simply returns *this. (This iterator does not "move".).

Definition at line 556 of file stl_iterator.h.

insert_iterator& 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
