Detailed Description

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

Turns assignment into insertion.

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

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

Member Typedef Documentation

container_type

template<typename _Container >

typedef _Container std::front_insert_iterator< _Container >::container_type

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

Definition at line 578 of file bits/stl_iterator.h.

difference_type

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 125 of file stl_iterator_base_types.h.

iterator_category

typedef output_iterator_tag std::iterator< output_iterator_tag , void , void , void , void >::iterator_category

inherited

One of the tag types.

Definition at line 121 of file stl_iterator_base_types.h.

pointer

typedef void std::iterator< output_iterator_tag , void , void , void , void >::pointer

inherited

This type represents a pointer-to-value_type.

Definition at line 127 of file stl_iterator_base_types.h.

reference

typedef void std::iterator< output_iterator_tag , void , void , void , void >::reference

inherited

This type represents a reference-to-value_type.

Definition at line 129 of file stl_iterator_base_types.h.

value_type

typedef void std::iterator< output_iterator_tag , void , void , void , void >::value_type

inherited

The type "pointed to" by the iterator.

Definition at line 123 of file stl_iterator_base_types.h.

Constructor & Destructor Documentation

front_insert_iterator()

template<typename _Container >

std::front_insert_iterator< _Container >::front_insert_iterator ( _Container &  __x )

inlineexplicit

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

Definition at line 581 of file bits/stl_iterator.h.

Member Function Documentation

operator*()

template<typename _Container >

front_insert_iterator& std::front_insert_iterator< _Container >::operator* ( )

inline

Simply returns *this.

Definition at line 620 of file bits/stl_iterator.h.

operator++() [1/2]

template<typename _Container >

front_insert_iterator& std::front_insert_iterator< _Container >::operator++ ( )

inline

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

Definition at line 625 of file bits/stl_iterator.h.

operator++() [2/2]

template<typename _Container >

front_insert_iterator std::front_insert_iterator< _Container >::operator++ ( int  )

inline

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

Definition at line 630 of file bits/stl_iterator.h.

operator=()

template<typename _Container >

front_insert_iterator& std::front_insert_iterator< _Container >::operator= ( const typename _Container::value_type &  __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 doesn't really have a position in the container (you can think of the position as being permanently at the front, if you like). Assigning a value to the iterator will always prepend the value to the front of the container.
