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.

Returns

This function will insert an object of type T constructed with T(std::forward<Args>(args)…) before the specified location. Due to the nature of a list this operation can be done in constant time, and does not invalidate iterators and references.

Parameters

Returns

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.

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.
