Detailed Description
template<typename _Tp, typename _Alloc = allocator<_Tp>>class
std::forward_list< _Tp, _Alloc >
A standard container with linear time access to elements, and fixed
time insertion/deletion at any point in the sequence.
Template Parameters:
_Tp Type of element.
_Alloc Allocator type, defaults to allocator<_Tp>.
Meets the requirements of a container, a sequence, including the
optional sequence requirements with the exception of at and operator[].
This is a singly linked list. Traversal up the list requires linear
time, but adding and removing elements (or nodes) is done in constant
time, regardless of where the change takes place. Unlike std::vector
and std::deque, random-access iterators are not provided, so
subscripting ( [] ) access is not allowed. For algorithms which only
need sequential access, this lack makes no difference.
Also unlike the other standard containers, std::forward_list provides
specialized algorithms unique to linked lists, such as splicing,
sorting, and in-place reversal.

void std::forward_list< _Tp, _Alloc >::assign (_InputIterator__first,
_InputIterator__last) [inline]
Assigns a range to a forward_list.
Parameters:
__first An input iterator.
__last An input iterator.
This function fills a forward_list with copies of the elements in the
range [__first,__last).
Note that the assignment completely changes the forward_list and that
the number of elements of the resulting forward_list is the same as the
number of elements assigned. Old data is lost.

Parameters:
__n Number of elements to be assigned.

Constructs object in forward_list after the specified iterator.
Parameters:
__pos A const_iterator into the forward_list.
__args Arguments.
Returns:
An iterator that points to the inserted data.
This function will insert an object of type T constructed with
T(std::forward<Args>(args)...) after the specified location. Due to the
nature of a forward_list this operation can be done in constant time,

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. Managing the pointer is the user's responsibility.

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

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 forward_list this operation can be done in constant
time, and does not invalidate iterators and references.

Reverse the elements in list. Reverse the order of elements in the list
in linear time.
Definition at line 1218 of file forward_list.h.
template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::sort () [inline]
Sort the elements of the list. Sorts the elements of this list in NlogN
time. Equivalent elements remain in list order.
Definition at line 1199 of file forward_list.h.
template<typename _Tp , class _Alloc > template<typename _Comp > void
forward_list::sort (_Comp__comp)
Sort the forward_list using a comparison function. Sorts the elements
of this list in NlogN time. Equivalent elements remain in list order.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::splice_after (const_iterator__pos,
forward_list< _Tp, _Alloc > &&__list) [inline]
Insert contents of another forward_list.
Parameters:
__pos Iterator referencing the element to insert after.
__list Source list.
The elements of list are inserted in constant time after the element
referenced by pos. list becomes an empty list.
Requires this != x.
Definition at line 1044 of file forward_list.h.
template<typename _Tp , typename _Alloc > void forward_list::splice_after
(const_iterator__pos, forward_list< _Tp, _Alloc > &&__list,
const_iterator__i)
Insert element from another forward_list.
Parameters:
__pos Iterator referencing the element to insert after.
__list Source list.
__i Iterator referencing the element before the element to move.
Removes the element in list list referenced by i and inserts it into
the current list after pos.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::splice_after (const_iterator__pos,
forward_list< _Tp, _Alloc > &&, const_iterator__before,
const_iterator__last) [inline]
Insert range from another forward_list.
Parameters:
__pos Iterator referencing the element to insert after.
__list Source list.
__before Iterator referencing before the start of range in list.
__last Iterator referencing the end of range in list.
Removes elements in the range (__before,__last) and inserts them after
__pos in constant time.
Undefined if __pos is in (__before,__last).

template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::std::swap
(this->_M_impl._M_head._M_next, __list._M_impl._M_head._M_next)
Swaps data with another forward_list.
Parameters:
__list A forward_list of the same element and allocator types.
This exchanges the elements between two lists in constant time. Note
that the global std::swap() function is specialized such that
std::swap(l1,l2) will feed to this function.
template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::unique () [inline]
Remove consecutive duplicate elements. For each consecutive set of
elements with the same value, remove all but the first one. Remaining
elements stay in list order. Note 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. Managing the pointer is
the user's responsibility.
Definition at line 1136 of file forward_list.h.
template<typename _Tp , typename _Alloc > template<typename _BinPred > void
forward_list::unique (_BinPred__binary_pred)
Remove consecutive elements satisfying a predicate.
Parameters:
__binary_pred Binary predicate function or object.
For each consecutive set of elements [first,last) that satisfy
predicate(first,i) where i is an iterator in [first,last), remove all
but the first one. Remaining elements stay in list order. Note 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. Managing the pointer is the user's responsibility.
