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 803 of file bits/stl_iterator.h.

difference_type

template<typename _Container >

using std::front_insert_iterator< _Container >::difference_type = ptrdiff_t

Definition at line 805 of file bits/stl_iterator.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 130 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 136 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 138 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 132 of file stl_iterator_base_types.h.

Constructor & Destructor Documentation

front_insert_iterator()

template<typename _Container >

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

inlineexplicitconstexpr

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

Definition at line 810 of file bits/stl_iterator.h.

Member Function Documentation

operator*()

template<typename _Container >

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

inlineconstexpr

Simply returns *this.

Definition at line 852 of file bits/stl_iterator.h.

operator++() [1/2]

template<typename _Container >

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

inlineconstexpr

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

Definition at line 858 of file bits/stl_iterator.h.

operator++() [2/2]

template<typename _Container >

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

inlineconstexpr

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

Definition at line 864 of file bits/stl_iterator.h.

operator=() [1/2]

template<typename _Container >

constexpr front_insert_iterator & std::front_insert_iterator< _Container >::operator= ( const typename _Container::value_type &  __value )

inlineconstexpr

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.

Definition at line 834 of file bits/stl_iterator.h.

operator=() [2/2]

template<typename _Container >

constexpr front_insert_iterator & std::front_insert_iterator< _Container >::operator= ( typename _Container::value_type &&  __value )

inlineconstexpr

Definition at line 842 of file bits/stl_iterator.h.
