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 insert_iterator (_Container &__x, _Iter __i)
constexpr insert_iterator & operator* ()
Simply returns *this. constexpr insert_iterator & operator++ ()
Simply returns *this. (This iterator does not move.) constexpr insert_iterator & operator++ (int)
Simply returns *this. (This iterator does not move.) constexpr insert_iterator & operator= (const typename _Container::value_type &__value)
constexpr insert_iterator & operator= (typename _Container::value_type &&__value)

_Iter iter

template<typename _Container>¶

class std::insert_iterator< _Container >"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.

template<typename _Container > typedef _Container std::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::insert_iterator< _Container >::insert_iterator (_Container & __x, _Iter __i) [inline], [constexpr]¶

The only way to create this iterator is with a container and an initial position (a normal iterator into the container).

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

Simply returns *this.

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

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

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

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

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

Parameters

Returns

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
