Detailed Description

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

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

Definition at line 404 of file stl_iterator.h.

typedef _Distance std::iterator::difference_type [inherited]

Distance between iterators is represented as this type.

Definition at line 126 of file stl_iterator_base_types.h.

typedef _Category std::iterator::iterator_category [inherited]

One of the tag types.

Definition at line 122 of file stl_iterator_base_types.h.

typedef _Pointer std::iterator::pointer [inherited]

This type represents a pointer-to-value_type.

Definition at line 128 of file stl_iterator_base_types.h.

typedef _Reference std::iterator::reference [inherited]

This type represents a reference-to-value_type.

Definition at line 130 of file stl_iterator_base_types.h.

typedef _Tp std::iterator::value_type [inherited]

The type "pointed to" by the iterator.

Definition at line 124 of file stl_iterator_base_types.h.


Constructor & Destructor Documentation

std::back_insert_iterator::back_insert_iterator ( _Container &  __x) [inline, explicit]

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

Definition at line 408 of file stl_iterator.h.


Member Function Documentation

back_insert_iterator& std::back_insert_iterator::operator* ( ) [inline]

Simply returns *this.

Definition at line 446 of file stl_iterator.h.

back_insert_iterator& std::back_insert_iterator::operator++ ( ) [inline]

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

Definition at line 451 of file stl_iterator.h.

back_insert_iterator std::back_insert_iterator::operator++ ( int  ) [inline]

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

Definition at line 456 of file stl_iterator.h.

back_insert_iterator& std::back_insert_iterator::operator= ( const typename _Container::value_type &  __value) [inline]
Parameters:
valueAn 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.
