Abstract

A linked list has an associated auxiliary data structure, containing external references to the linked list which are used by updating tasks. The auxiliary data structure is used to block subsets of the linked list from being altered by other tasks. Preferably, the linked list is doubly-linked, and list maintenance is accomplished using object-oriented programming techniques. The auxiliary data structure is an object, which comprises iterator objects, including inspector objects and mutator objects, blocker objects and view objects. Iterator objects are used by clients to access the linked list externally. An inspector object traverses the list without changing it; while a mutator alters the list, and may traverse it as well. By blocking only a relatively small portion of a large linked list, multiple tasks may concurrently access different list elements and perform separate list updates. <IMAGE>
