Detailed Description

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

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

Definition at line 590 of file stl_iterator.h.

typedef _Distance std::iterator::difference_type [inherited]

Distance between iterators is represented as this type.

Definition at line 126 of file stl_iterator_base_types.h.

typedef _Category std::iterator::iterator_category [inherited]

One of the tag types.

Definition at line 122 of file stl_iterator_base_types.h.

typedef _Pointer std::iterator::pointer [inherited]

This type represents a pointer-to-value_type.

Definition at line 128 of file stl_iterator_base_types.h.

typedef _Reference std::iterator::reference [inherited]

This type represents a reference-to-value_type.

Definition at line 130 of file stl_iterator_base_types.h.

typedef _Tp std::iterator::value_type [inherited]

The type "pointed to" by the iterator.

Definition at line 124 of file stl_iterator_base_types.h.

Constructor & Destructor Documentation

std::insert_iterator::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 596 of file stl_iterator.h.

Member Function Documentation

insert_iterator& std::insert_iterator::operator* ( ) [inline]

Simply returns *this.

Definition at line 650 of file stl_iterator.h.

insert_iterator& std::insert_iterator::operator++ ( ) [inline]

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

Definition at line 655 of file stl_iterator.h.

insert_iterator& std::insert_iterator::operator++ ( int  ) [inline]

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

Definition at line 660 of file stl_iterator.h.

insert_iterator& std::insert_iterator::operator= ( const typename _Container::value_type &  __value) [inline]
valueAn instance of whatever type container_type::const_reference is; presumably a reference-to-const T for container<T>.
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
