List of all members.

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.

Member Typedef Documentation

template<typename _Container>
typedef _Container std::back_insert_iterator< _Container >::container_type

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

Definition at line 394 of file stl_iterator.h.

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Distance std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::difference_type [inherited]

Distance between iterators is represented as this type.

Reimplemented in std::reverse_iterator< _Iterator >.

Definition at line 117 of file stl_iterator_base_types.h.

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Category std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::iterator_category [inherited]

One of the tag types.

Definition at line 113 of file stl_iterator_base_types.h.

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Pointer std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::pointer [inherited]

This type represents a pointer-to-value_type.

Reimplemented in __gnu_cxx::_Rope_const_iterator< _CharT, _Alloc >, __gnu_cxx::_Rope_iterator< _CharT, _Alloc >, std::_Bit_iterator, std::_Bit_const_iterator, and std::reverse_iterator< _Iterator >.

Definition at line 119 of file stl_iterator_base_types.h.

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Reference std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::reference [inherited]

This type represents a reference-to-value_type.

Reimplemented in __gnu_cxx::_Rope_const_iterator< _CharT, _Alloc >, __gnu_cxx::_Rope_iterator< _CharT, _Alloc >, std::_Bit_iterator, std::_Bit_const_iterator, and std::reverse_iterator< _Iterator >.

Definition at line 121 of file stl_iterator_base_types.h.

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Tp std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::value_type [inherited]

The type "pointed to" by the iterator.

Reimplemented in __gnu_cxx::sequence_buffer< _Sequence, _Buf_sz >.

Constructor & Destructor Documentation

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

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

Definition at line 398 of file stl_iterator.h.


Member Function Documentation

template<typename _Container>
back_insert_iterator& std::back_insert_iterator< _Container >::operator * (  )  [inline]

Simply returns *this.

Definition at line 429 of file stl_iterator.h.

template<typename _Container>
back_insert_iterator std::back_insert_iterator< _Container >::operator++ ( int   )  [inline]

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

Definition at line 439 of file stl_iterator.h.

template<typename _Container>
back_insert_iterator& std::back_insert_iterator< _Container >::operator++ (  )  [inline]

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

Definition at line 434 of file stl_iterator.h.

template<typename _Container>
back_insert_iterator& std::back_insert_iterator< _Container >::operator= ( typename _Container::const_reference  __value  )  [inline]

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 end, if you like). Assigning a value to the iterator will always append the value to the end of the container.
