Detailed Description

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

Turns assignment into insertion.

These are output iterators, constructed from a container-of-T. Assigning a T to the iterator appends it to the container using push_back.

Tip: Using the back_inserter function to create these iterators can save typing.

Member Typedef Documentation

template<typename _Container >
typedef _Container std::back_insert_iterator< _Container >::container_type

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

Definition at line 404 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 126 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 122 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 128 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 130 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 124 of file stl_iterator_base_types.h.

Constructor & Destructor Documentation

template<typename _Container >
std::back_insert_iterator< _Container >::back_insert_iterator ( _Container &  __x)
inlineexplicit

The only way to create this iterator is with a container.

Definition at line 408 of file stl_iterator.h.

Member Function Documentation

template<typename _Container >
back_insert_iterator& std::back_insert_iterator< _Container >::operator* ( )
inline

Simply returns *this.

Definition at line 446 of file stl_iterator.h.

template<typename _Container >
back_insert_iterator& std::back_insert_iterator< _Container >::operator++ ( )
inline

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

Definition at line 451 of file stl_iterator.h.

template<typename _Container >
back_insert_iterator std::back_insert_iterator< _Container >::operator++ ( int  )
inline

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

Definition at line 456 of file stl_iterator.h.

template<typename _Container >
back_insert_iterator& std::back_insert_iterator< _Container >::operator= ( const typename _Container::value_type &  __value)
inline
Parameters
valueAn 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 doesn't really have a position in the container (you can think of the position as being permanently at the end, if you like). Assigning a value to the iterator will always append the value to the end of the container.
