Detailed Description
template<typename _Tp, typename _Alloc = std::allocator<_Tp>>class std::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 reversible container, and a sequence, including
the optional sequence requirements with the exception of at and operator[].
This is a doubly linked list. Traversal up and down 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::list provides specialized algorithms
unique to linked lists, such as splicing, sorting, and in-place reversal.
A couple points on memory allocation for list<Tp>:
First, we never actually allocate a Tp, we allocate List_node<Tp>'s and trust [20.1.5]/4
to DTRT. This is to ensure that after elements from list<X,Alloc1> are spliced into
list<X,Alloc2>, destroying the memory of the second list is a valid operation, i.e.,
Alloc1 giveth and Alloc2 taketh away.
Second, a list conceptually represented as
A <---> B <---> C <---> D
is actually circular; a link exists between A and D. The list class holds (as its only
data member) a private list::iterator pointing to D, not to A! To get to the head of the
list, we start at the tail and move forward by one. When this member iterator's
next/previous pointers refer to itself, the list is empty.

template<typename _Tp , typename _Alloc > list< _Tp, _Alloc >::iterator list::erase
(iterator__position)
Remove element at given position.
Parameters:
__position 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 list by
one.
Due to the nature of a 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

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> iterator std::list< _Tp, _Alloc

Remove a range of elements.
Parameters:
__first Iterator pointing to 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 [first,last) and shorten the 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

This is a typical stack operation. The function creates an element at the end of the list
and assigns the given data to it. Due to the nature of a list this operation can be done
in constant time, and does not invalidate iterators and references.

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> void std::list< _Tp, _Alloc
>::push_front (const value_type &__x) [inline]
Add data to the front of the list.
Parameters:
__x Data to be added.
This is a typical stack operation. The function creates an element at the front of the
list and assigns the given data to it. Due to the nature of a list this operation can be
done in constant time, and does not invalidate iterators and references.

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> reverse_iterator std::list< _Tp,

Iteration is done in reverse element order.
Definition at line 775 of file stl_list.h.
template<typename _Tp, typename _Alloc = std::allocator<_Tp>> const_reverse_iterator
std::list< _Tp, _Alloc >::rbegin () const [inline]

template<typename _Tp, typename _Alloc > void list::remove (const _Tp &__value)
Remove all elements equal to value.
Parameters:
__value The value to remove.
Removes every element in the list equal to value. 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.

template<typename _Tp , typename _Alloc > template<typename _Predicate > void list::remove_if
(_Predicate__pred)
Remove all elements satisfying a predicate.
Template Parameters:
_Predicate Unary predicate function or object.
Removes every element in the list for which the predicate returns true. 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.

template<typename _Tp , typename _Alloc > void list::resize (size_type__new_size)
Resizes the list to the specified number of elements.
Parameters:
__new_size Number of elements the list should contain.
This function will resize the list to the specified number of elements. If the number is
smaller than the list's current size the list is truncated, otherwise default constructed
elements are appended.

template<typename _Tp , typename _Alloc > void list::resize (size_type__new_size, const
value_type &__x)
Resizes the list to the specified number of elements.
Parameters:
__new_size Number of elements the list should contain.
__x Data with which new elements should be populated.
This function will resize the list to the specified number of elements. If the number is
smaller than the list's current size the list is truncated, otherwise the list is extended
and new elements are populated with given data.

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> void std::list< _Tp, _Alloc
>::splice (iterator__position, list< _Tp, _Alloc > &&__x) [inline]
Insert contents of another list.
Parameters:
__position Iterator referencing the element to insert before.
__x Source list.
The elements of __x are inserted in constant time in front of the element referenced by
__position. __x becomes an empty list.
Requires this != __x.

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> void std::list< _Tp, _Alloc

Insert element from another list.
Parameters:
__position Iterator referencing the element to insert before.
__x Source list.
__i Iterator referencing the element to move.
Removes the element in list __x referenced by __i and inserts it into the current list
before __position.

template<typename _Tp, typename _Alloc = std::allocator<_Tp>> void std::list< _Tp, _Alloc

[inline]
Insert range from another list.
Parameters:
__position Iterator referencing the element to insert before.
__x Source list.
__first Iterator referencing the start of range in x.
__last Iterator referencing the end of range in x.
Removes elements in the range [__first,__last) and inserts them before __position in
constant time.

Swaps data with another list.
Parameters:
__x A 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 > void list::unique ()
Remove consecutive duplicate elements. For each consecutive set of elements with the same

pointed-to memory is not touched in any way. Managing the pointer is the user's

Template Parameters:
_BinaryPredicate 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
