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.

	)

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.

Template Parameters

Parameters

__x	Sorted list to merge.

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.

inlinenoexcept

Removes first 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 first element's data is needed, it should be retrieved before pop_front() is called.

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

void std::list< _Tp, _Alloc >::push_back ( const value_type & __x )

inline

Add data to the end of the list.

Parameters

__x	Data to be added.

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.

Definition at line 1018 of file stl_list.h.

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.

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 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 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.

	)

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

__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.

void list::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.
