Public Types¶

typedef _Container container_type
A nested typedef for the type of whatever container you used. using difference_type = ptrdiff_t
typedef output_iterator_tag iterator_category
One of the tag types. typedef void pointer
This type represents a pointer-to-value_type. typedef void reference
This type represents a reference-to-value_type. typedef void value_type
The type 'pointed to' by the iterator.

Public Member Functions¶

constexpr front_insert_iterator (_Container &__x)
The only way to create this iterator is with a container. constexpr front_insert_iterator & operator* ()
Simply returns *this. constexpr front_insert_iterator & operator++ ()
Simply returns *this. (This iterator does not move.) constexpr front_insert_iterator operator++ (int)
Simply returns *this. (This iterator does not move.) constexpr front_insert_iterator & operator= (const typename _Container::value_type &__value)
constexpr front_insert_iterator & operator= (typename _Container::value_type &&__value)

Protected Attributes¶

_Container * container

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.

template<typename _Container > typedef _Container std::front_insert_iterator< _Container >::container_type¶

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

typedef output_iterator_tag std::iterator< output_iterator_tag , void , void , void , void >::iterator_category [inherited]¶

One of the tag types.

typedef void std::iterator< output_iterator_tag , void , void , void , void >::pointer [inherited]¶

This type represents a pointer-to-value_type.

typedef void std::iterator< output_iterator_tag , void , void , void , void >::reference [inherited]¶

This type represents a reference-to-value_type.

typedef void std::iterator< output_iterator_tag , void , void , void , void >::value_type [inherited]¶

The type 'pointed to' by the iterator.

template<typename _Container > constexpr std::front_insert_iterator< _Container >::front_insert_iterator (_Container & __x) [inline], [explicit], [constexpr]¶

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

template<typename _Container > constexpr front_insert_iterator & std::front_insert_iterator< _Container >::operator* () [inline], [constexpr]¶

Simply returns *this.

template<typename _Container > constexpr front_insert_iterator & std::front_insert_iterator< _Container >::operator++ () [inline], [constexpr]¶

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

template<typename _Container > constexpr front_insert_iterator std::front_insert_iterator< _Container >::operator++ (int) [inline], [constexpr]¶

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

template<typename _Container > constexpr front_insert_iterator & std::front_insert_iterator< _Container >::operator= (const typename _Container::value_type & __value) [inline], [constexpr]¶

Parameters

Returns

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.
