Detailed Description

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

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.

Member Function Documentation

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

template<typename _InputIterator>

void std::list< _Tp, _Alloc >::assign	(	_InputIterator	__first,

Assigns a range to a list.

Parameters:

	first	An input iterator.
	last	An input iterator.

This function fills a list with copies of the elements in the range [first,last).

Note that the assignment completely changes the list and that the resulting list's size is the same as the number of elements assigned. Old data may be lost.

Parameters:

	n	Number of elements to be assigned.
	val	Value to be assigned.

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

iterator std::list< _Tp, _Alloc >::erase	(	iterator	__first,
		iterator	__last
	)			[inline]

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.

template<typename _Tp, typename _Alloc>

list< _Tp, _Alloc >::iterator std::list< _Tp, _Alloc >::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.

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.

Undefined if position is in [first,last).

void std::list< _Tp, _Alloc >::splice	(	iterator	__position,
		list< _Tp, _Alloc > &	__x,
		iterator	__i
	)			[inline]

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 >::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.

__x

)

[inline]

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 _BinaryPredicate>

void std::list< _Tp, _Alloc >::unique

(

_BinaryPredicate

)

Remove consecutive elements satisfying a predicate.

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 pointer is the user's responsibilty.

Reimplemented in std::__debug::list< _Tp, _Allocator >.

)

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 responsibilty.
