NAME

       std::back_insert_iterator< _Container > - Turns assignment into insertion.

SYNOPSIS

       Inherits std::iterator< output_iterator_tag, void, void, void, void >.

   Public Types
       typedef _Container container_type
           A nested typedef for the type of whatever container you used.
       typedef void difference_type
           Distance between iterators is represented as this 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.

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

   Protected Attributes
       _Container * container

Detailed Description

   template<typename _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.
