std::back_insert_iterator - Man Page

typedef _Container container_type
A nested typedef for the type of whatever container you used.
using difference_type
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.

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

_Container * 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.

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

One of the tag types.

This type represents a pointer-to-value_type.

This type represents a reference-to-value_type.

The type 'pointed to' by the iterator.

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

Simply returns *this.

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

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

Parameters

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.
