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.

Template Parameters

_Tp	Type of element.
_Alloc	Allocator type, defaults to allocator<_Tp>.

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.

noexcept

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 responsibility.

Referenced by std::list< __inp, __rebind_inp >::erase().

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

iterator std::list< _Tp, _Alloc >::erase ( const_iterator  __first, const_iterator  __last  )

inlinenoexcept

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 responsibility.

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

(

list< _Tp, _Alloc > &&

__x

)

Merge sorted lists.

Parameters

__x	Sorted list to merge.

Assumes that both __x and this list are sorted according to operator<(). Merges elements of __x into this list in sorted order, leaving __x empty when complete. Elements in this list precede elements in __x that are equal.

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

template<typename _StrictWeakOrdering >

void std::list< _Tp, _Alloc >::merge	(	list< _Tp, _Alloc > &&	__x,
		_StrictWeakOrdering	__comp

Merge sorted lists according to comparison function.

Template Parameters

_StrictWeakOrdering

Comparison function defining sort order.

Parameters

__x	Sorted list to merge.
__comp	Comparison functor.

Assumes that both __x and this list are sorted according to StrictWeakOrdering. Merges elements of __x into this list in sorted order, leaving __x empty when complete. Elements in this list precede elements in __x that are equivalent according to StrictWeakOrdering().

list& std::list< _Tp, _Alloc >::operator=

(

const list< _Tp, _Alloc > &

__x

)

List assignment operator.

No explicit dtor needed as the _Base dtor takes care of things. The _Base dtor only erases the elements, and note 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.

Parameters

__x	A list of identical element and allocator types.

All the elements of __x are copied, but unlike the copy constructor, the allocator object is not copied.

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

list& std::list< _Tp, _Alloc >::operator= ( list< _Tp, _Alloc > &&  __x )

inline

List move assignment operator.

Parameters

__x	A list of identical element and allocator types.

The contents of __x are moved into this list (without copying). __x is a valid, but unspecified list

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

list& std::list< _Tp, _Alloc >::operator= ( initializer_list< value_type >  __l )

inline

List initializer list assignment operator.

Parameters

__l	An initializer_list of value_type.

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

void std::list< _Tp, _Alloc >::pop_back ( )

inlinenoexcept

Removes last element.

This is a typical stack operation. It shrinks 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.

Note that no data is returned, and if the last element's data is needed, it should be retrieved before pop_back() is called.

Add data to the end of the list.

Parameters

__x	Data to be added.

__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 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.

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

	)

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.

inlinenoexcept

Insert contents of another list.

Parameters

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

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

(

)

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.

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.
