- This specialization is intended for so-called persistent usage when no item
+ This specialization is append-only list when no item
reclamation may be performed. The class does not support deleting of list item.
- Usually, ordered single-linked list is used as a building block for the hash table implementation.
- The complexity of searching is <tt>O(N)</tt>.
-
- See \ref cds_nonintrusive_LazyList_gc "LazyList" for description of template parameters.
-
- The interface of the specialization is a little different.
