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.
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.
A couple points on memory allocation for forward_list<Tp>:
First, we never actually allocate a Tp, we allocate Fwd_list_node<Tp>'s
and trust [20.1.5]/4 to DTRT. This is to ensure that after elements
from forward_list<X,Alloc1> are spliced into forward_list<X,Alloc2>,
destroying the memory of the second list is a valid operation, i.e.,
Alloc1 giveth and Alloc2 taketh away.

the user's responsibility.

template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator
std::forward_list< _Tp, _Alloc >::erase_after (const_iterator __pos,
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:
An iterator pointing to the element pointed to by last prior to
erasing (or end()).
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.
Definition at line 969 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 to element to be erased.
Returns:
An iterator pointing to the next element (or end()).
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

template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::resize (size_type __sz) [inline]
Resizes the forward_list to the specified number of elements.
Parameters:
sz Number of elements the forward_list should contain.
This function will resize the forward_list to the specified number of
elements. If the number is smaller than the forward_list's current size
the forward_list is truncated, otherwise the forward_list is extended
and new elements are populated with given data.

std::forward_list< _Tp, _Alloc >::reverse () [inline]
Reverse the elements in list. Reverse the order of elements in the list
in linear time.

_Comp > void std::forward_list< _Tp, _Alloc >::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.

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).

std::forward_list< _Tp, _Alloc >::splice_after (const_iterator __pos,

Insert element from another forward_list. Parameters:
pos Iterator referencing the element to insert after.
list Source list.
it 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 > void std::forward_list< _Tp,

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.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void
std::forward_list< _Tp, _Alloc >::swap (forward_list< _Tp, _Alloc > &&
__list) [inline]
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 > template<typename _BinPred > void
std::forward_list< _Tp, _Alloc >::unique (_BinPred __binary_pred)
[inline]
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.

Remove consecutive duplicate elements. For each consecutive set of

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
