forward_list.
__args Arguments.
Returns:
An iterator that points to the inserted
data.
This function will insert an object of type T constructed with

Definition at line 699 of file forward_list.h.template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator std::forward_list< _Tp, _Alloc >::erase_after ( const_iterator__pos) [inline]¶
Removes the element pointed to by the iterator following pos. Parameters:__pos Iterator pointing before element
to be erased.
Returns:
An iterator pointing to the element following
the one that was erased, or end() if no such element exists.
This function will erase the element at the given position and thus shorten the
forward_list by one.
Due to the nature of a forward_list this operation can be done in constant time,
and only invalidates iterators/references to the element being removed. The
user is also cautioned that this function only erases the element, and that if
the element is itself a pointer, the pointed-to memory is not touched in any
way. Managing the pointer is the user's responsibility.

template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator std::forward_list< _Tp, _Alloc >::erase_after ( const_iterator__pos, const_iterator__last) [inline]¶
Remove a range of elements. Parameters:__pos Iterator pointing before the
first element to be erased.
__last Iterator pointing to one past the last element to be erased.
Returns:
@ __last.
This function will erase the elements in the range (pos,last) and
shorten the forward_list accordingly.
This operation is linear time in the size of the range and only invalidates
iterators/references to the element being removed. The user is also cautioned
that this function only erases the elements, and that if the elements
themselves are pointers, the pointed-to memory is not touched in any way.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::pop_front () [inline]¶
Removes first element. This is a typical stack operation. It shrinks the forward_list by one. Due to the nature of a forward_list this operation can be done in constant time, and only invalidates iterators/references to the element being removed. Note that no data is returned, and if the first element's data is needed, it should be retrieved before pop_front() is called.

Add data to the front of the forward_list. Parameters:__val Data to be added.
This is a typical stack operation. The function creates an element at the front
of the forward_list and assigns the given data to it. Due to the nature of a
