Detailed Description

template<typename _Container>
class std::front_insert_iterator< _Container >

Turns assignment into insertion.

These are output iterators, constructed from a container-of-T. Assigning a T to the iterator prepends it to the container using push_front.

Tip: Using the front_inserter function to create these iterators can save typing.

Member Function Documentation

template<typename _Container>

front_insert_iterator& std::front_insert_iterator< _Container >::operator * ( ) [inline]

Simply returns *this.

Definition at line 491 of file stl_iterator.h.

template<typename _Container>

front_insert_iterator std::front_insert_iterator< _Container >::operator++ ( int ) [inline]

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

Definition at line 501 of file stl_iterator.h.

template<typename _Container>

front_insert_iterator& std::front_insert_iterator< _Container >::operator++ ( ) [inline]

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

Definition at line 496 of file stl_iterator.h.

template<typename _Container>

front_insert_iterator& std::front_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 front, if you like). Assigning a value to the iterator will always prepend the value to the front of the container.
