2.3.8. Singly linked lists (class slist)

Learning objectives

The class slist

Besides doubly linked lists of type list, LEDA also offers singly linked lists. The respective class is called slist. Here, every container knows only its successor, but not its predecessor. This implementation is particularly memory efficient; in exchange, an slist can be passed through only from the front to behind, but not vice-versa. Figure 2.16 shows a singly linked list.

The interface of slist is fundamentally smaller than the one of list. One should use this type only if memory is scarce and if one must iterate only in one direction.

More information about singly linked lists is found on the corresponding manual page.
