Detailed Description¶
template<typename _Tp, typename _Alloc = allocator<_Tp>>class std::forward_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 sequence, including the optional
sequence requirements with the exception of at and operator[].
This is a singly linked list. Traversal up 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::forward_list provides
specialized algorithms unique to linked lists, such as splicing, sorting, and
in-place reversal.

Removes the element pointed to by the iterator following pos. Parameters:__pos Iterator pointing before element to be
erased.
Returns:
An iterator pointing to the element following the one
that was erased, or end() if no such element exists.
This function will erase the element at the given position and thus shorten the
forward_list by one.
Due to the nature of a forward_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.

template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator std::forward_list< _Tp, _Alloc >::erase_after ( const_iterator__pos, const_iterator__last) [inline]¶
Remove a range of elements. Parameters:__pos Iterator pointing before the first element
to be erased.
__last Iterator pointing to one past the last element to be erased.
Returns:
@ __last.
This function will erase the elements in the range (__pos,__last) and
shorten the forward_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 = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::pop_front () [inline]¶
Removes first element. This is a typical stack operation. It shrinks the forward_list by one. Due to the nature of a forward_list this operation can be done in constant time, and only invalidates iterators/references to the element being removed.

Remove all elements equal to value. Parameters:__val The value to remove.
Removes every element in the list equal to __val. 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.

Remove all elements satisfying a predicate. Parameters:__pred Unary predicate function or object.
Removes every element in the list for which the predicate returns true.

Resizes the forward_list to the specified number of elements. Parameters:__sz Number of elements the forward_list should
contain.
This function will resize the forward_list to the specified number of elements.
If the number is smaller than the forward_list's current number of elements
