The MFC template class CList implements a generic linked list that can be customized to work with any data type POSITION : A value used to denote the position of an element in a collection; used by MFC collection classes LIST Sample : CObList Construction CObList Constructs an empty list for CObject pointers. Head/Tail Access GetHead Returns the head element of the list (cannot be empty). GetTail Returns the tail element of the list (cannot be empty). Operations RemoveHead Removes the element from the head of the list. RemoveTail Removes the element from the tail of the list. AddHead Adds an element (or all the elements in another list) to the head of the list (makes a new head). AddTail Adds an element (or all the elements in another list) to the tail of the list (makes a new tail). RemoveAll Removes all the elements from this list. LIST .
